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 ).

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 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.


How do you get leading coefficient?

The leading coefficient of a polynomial is the coefficient of the term with the highest degree. To find it, first identify the term that has the largest exponent, and then take the coefficient of that term. For example, in the polynomial (3x^4 + 2x^2 - 5), the leading coefficient is 3, as it corresponds to the (x^4) term.


Give the degree and the leading coefficient of the polynomial 9x-45x- squared -4x to the third power?

The polynomial can be rewritten as (-4x^3 - 45x^2 + 9x). The degree of the polynomial is 3, which is determined by the highest exponent of (x). The leading coefficient, which is the coefficient of the term with the highest degree, is (-4).


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 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.


What is the leading coefficient in a polynomial?

It is the number (coefficient) that belongs to the variable of the highest degree in a polynomial.


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.

How can one find all rational roots of a polynomial equation?

To find all rational roots of a polynomial equation, you can use the Rational Root Theorem. This theorem states that any rational root of a polynomial equation in the form of (anxn an-1xn-1 ... a1x a0 0) must be a factor of the constant term (a0) divided by a factor of the leading coefficient (an). By testing these possible rational roots using synthetic division or polynomial long division, you can determine which ones are actual roots of the equation.

How could I compare and contrast rational and polynomial function properties?

Rational functions are ratios of two polynomial functions, which means they can exhibit unique behaviors such as asymptotes and discontinuities, while polynomial functions are continuous and smooth curves without breaks. Both types can have similar characteristics, such as degree and leading coefficient, which influence end behavior and intercepts. However, rational functions can approach vertical and horizontal asymptotes, while polynomial functions do not; they continue to rise or fall indefinitely. Ultimately, understanding these differences helps in analyzing their graphs and behaviors in various contexts.


Where p is a factor of the leading coefficient of the polynomial and q is a factor of the constant term.?

Anywhere. Provided it is not zero, and number p can be the leading coefficient of a polynomial. And any number q can be the constant term.
