What else can I help you with?
Are all polynomial function continuous?
Yes.
How do you find the zeros of cubic polynomial equation?
If the cubic polynomial you are given does not have an obvious factorization, then you must use synthetic division. I'm sure wikipedia can tell you all about that.
How do you figure out how many real zeros a problem has?
To find the number of real zeros of a function, you can use the Intermediate Value Theorem and graphing techniques to approximate the number of times the function crosses the x-axis. Additionally, you can apply Descartes' Rule of Signs or the Rational Root Theorem to analyze the possible real zeros based on the coefficients of the polynomial function.
Which of the following is a polynomial function in standard form with zeros at 8 1 and 3?
Please don't write "the following" if you don't provide a list - it doesn't make any sense.To obtain a polynomial with specific zeros, you write, in this case: (x - 8) (x - 1) (x - 3) Multiply all those together, and you get the polynomial in standard form. Note: for a negative zero, you would get a factor with a positive coefficient; for example, if you want a root of -4: (x - -4) = (x + 4)
Which fundamental functions have all real numbers as the domain?
The domains of polynomial, cosine, sine and exponential functions all contain the entire real number line. The domain of a rational function does not, since its denominator has zeros, and neither does the domain of a tangent function. (1/2)x = true (8/3)x = true
How different polynomial and non polynomial?
Well, "non-polynomial" can be just about anything; presumably you mean a non-polynomial FUNCTION, but there are lots of different types of functions. Polynomials, among other things, have the following properties - assuming you have an expression of the type y = P(x):* The polynomial is defined for any value of "x". * The polynomial makes is continuous; i.e., it doesn't make sudden "jumps". * Similarly, the first derivative, the second derivative, etc., are continuous. A non-polynomial function may not have all of these properties; for example: * A rational function is not defined at any point where the denominator is zero. * The square root function is not defined for negative values. * The first derivative (i.e., the slope) of the absolute value function makes a sudden jump at x = 0. * The function that takes the integer part of any real number makes sudden jumps at all integers.
How do you find all the zeros of a function?
You could try setting the function equal to zero, and finding all the solutions of the equation. Just a suggestion.
Is 0 a polynomial?
A polynomial is a function which can take the form: f(x) = sum(a_n * x^n) where n is a nonnegative integer. 0 is the constant function which can be represented in the form above by taking a_n = 0 for all n.
What is the difference between a power functions and a polynomial functions?
A power function is of the form xa where a is a real number. A polynomial function is of the form anxn + an-1xn-1 + ... + a1x + a0 for some positive integer n, and all the ai are real constants.
Can you have quadratic function with one real root and are complex root?
Yes, but in this case, the coefficients of the polynomial can not all be real.
How do you find the values of the polynomial function?
That all depends on the meaning of the context. If you want to determine the values of the polynomial function, then you need to substitute the value for the input variable of the function. Finally, evaluate it. For instance: f(x) = x + 2 If x = 2, then f(2) = 2 + 2 = 4.
What are the zeros of the tangent function?
All positive and negative multiples of 180 degrees. (pi radians)
