Determine whether​ f(x) represents a polynomial function. If​ possible, identify the degree and type of polynomial function.

Question

f(x)=3x-8x^2

 

If f(x) is a polynomial function, what is its degree?

 

 

 

If f(x) is a polynomial function, what is its type?

Answer 1

f(x)=3x-8x^2

 

Rearrange in descending order of exponents:

 

f(x) = -8x² + 3x

This is a quadratic polynomial of form: f(x) = ax² + bx + c

with a = -8, b = 3, c = 0

 

The degree of the polynomial equates to the highest exponent:

 

This is a quadratic polynomial of degree 2.

Answer 2

it is a polynomial function. It is a quadratic, degree 2
