If the degree of a polynomial function is even and the leading coefficient is negative then what will happen to the ends?
If a polynomial function has an even degree and a negative leading coefficient, the ends of the graph will both point downward. This means that as the input values approach positive or negative infinity, the output values will also approach negative infinity. In summary, the graph will have a "U" shape that opens downwards.
What is type a polynomial with integer coefficients and a leading coefficient of 1 in the box below?
A polynomial with integer coefficients and a leading coefficient of 1 is called a monic polynomial. An example of such a polynomial is ( f(x) = x^3 - 4x^2 + 6x - 2 ). In this polynomial, all coefficients are integers, and the leading term ( x^3 ) has a coefficient of 1.
Why in fourier series constant is divided by two?
In Fourier series, the constant term, or the average value of the function over one period, is divided by two when computing the Fourier coefficients. This is because the constant term corresponds to the zero-frequency component, which represents the average value of the periodic function. When calculating the Fourier series, the coefficients are derived from integrals that include the full period of the function, leading to the factor of ( \frac{1}{2} ) for the constant term to ensure accurate representation. This adjustment maintains the overall balance of the series in reconstructing the original function.
Can the leading coefficient of a polynomial function be a fraction?
Yes, the leading coefficient of a polynomial function can be a fraction. A polynomial is defined as a sum of terms, each consisting of a coefficient (which can be any real number, including fractions) multiplied by a variable raised to a non-negative integer power. Thus, the leading coefficient, which is the coefficient of the term with the highest degree, can indeed be a fraction.
What is a polynomial function f of least degree that has rational coefficient a leading coefficient of 1 and the given zeros -7 -4?
A polynomial function of least degree with rational coefficients and a leading coefficient of 1 that has the zeros -7 and -4 can be constructed using the fact that if ( r ) is a zero, then ( (x - r) ) is a factor. Therefore, the polynomial can be expressed as ( f(x) = (x + 7)(x + 4) ). Expanding this, we get ( f(x) = x^2 + 11x + 28 ). Thus, the polynomial function is ( f(x) = x^2 + 11x + 28 ).

When an odd function has a negative leading coefficient what happens to the graph?
the left end of the graph is going in a positive direction and the right end is going in a negative direction.
What is the rational zero theorem?
If a polynomial function, written in descending order, has integer coefficients, then any rational zero must be of the form ± p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.
Which polynomial has rational coefficients a leading leading coefficient of 1 and the zeros at 2-3i and 4?
There cannot be such a polynomial. If a polynomial has rational coefficients, then any complex roots must come in conjugate pairs. In this case the conjugate for 2-3i is not a root. Consequently, either (a) the function is not a polynomial, or (b) it does not have rational coefficients, or (c) 2 - 3i is not a root (nor any other complex number), or (d) there are other roots that have not been mentioned. In the last case, the polynomial could have any number of additional (unlisted) roots and is therefore indeterminate.

What is the end behavior of a function?
The end behavior of a function is how the function acts as it approaches infinity and negative infinity. All even functions such as x^2 approach infinity in the y-axis as x approaches infinity and odd functions such as x^3 approach positive infinity in the y- axis as x approaches positive infinity and negative infinity in the y- axis as x approaches negative infinity. If their is a negative leading coefficient then it is just flipped.

What is the effect of symmetry on the fourier series?
Symmetry in a function significantly simplifies its Fourier series representation. For even functions, only cosine terms are present, while odd functions contain only sine terms. This reduces the number of coefficients that need to be calculated, leading to a more straightforward analysis of the function's periodic behavior. Additionally, symmetry can enhance convergence properties, allowing for faster and more efficient approximations of the function.
What is the tanget of 90?
The tangent of 90 degrees is undefined. This is because the tangent function is defined as the ratio of the sine to the cosine, and at 90 degrees, the cosine is zero, leading to division by zero. Therefore, the tangent approaches infinity as the angle approaches 90 degrees.
Why does the square root function have a restricted domain?
The square root function has a restricted domain because it is defined only for non-negative real numbers. This restriction arises from the fact that the square root of a negative number is not a real number, leading to complex results instead. To ensure that the function produces real outputs, the domain is limited to zero and positive values. Hence, for the function ( f(x) = \sqrt{x} ), the domain is ( x \geq 0 ).
