Which of the following is a polynomial function? select all correct answers. select all that apply: f(x)=4⋅11x f(x)=3⋅18x f(x)=10⋅17x f(x)=−4x3−4x2+5x+1 f(x)=−2x−1

All of them are polynomial functions

Step-by-step explanation:

Remember that a polynomial function of x is a function whose value f(x) is always equal to for a fixed n≥0 (the degree of f) and fixed coefficients

For example, is a polynomial function, but is not because is not a nonnegative power of x. Another example of a non-polynomial function is .

f(x)=4⋅11x is polynomial with degree 1 and . For the same reasons, f(x)=3⋅18x and f(x)=10⋅17x are polynomial functions.

f(x)=−4x³−4x²+5x+1 is a polynomial function of degree 3 with . and f(x)=−2x−1 is a polynomial function of degree 1 and coefficients .

pi x^2
