What is a root of a polynomial function? a. a value of the variable that makes the polynomial equal to zero b. the coefficient of the leading term of the polynomial c. a coefficient of the polynomial that is equal to zero d. the value of the polynomial when zero is substituted for the variable

Root of a polynomial also known as zero of polynomial which means to find the root of polynomial we can set up the polynomial equal to zero to get the value ( root) of the variable.

In other words roots of a polynomial function is the number, when you will plug into the polynomial, it will make the polynomial zero.

Hence the correct choice is A: A value of the variable that makes the polynomial equal to zero .

Hope this helps you!

Answer is A.

Step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
