If a cubic polynomial has zeros at x= -4, x=0 and x=7, then

A). The polynomial has no imaginary zeros.

B). The polynomial as a pair of imaginary zeros.

A

Step-by-step explanation:

The Fundamental theorem of algebra tells us that a polynomial of degree n has n roots.

Here the polynomial is a cubic, that is of degree 3

Thus it will have 3 roots, real and/ or imaginary.

Since imaginary roots occur in conjugate pairs

Since the polynomial has 3 real roots there are no imaginary roots, thus

A is the required response.

i think that you should ask google for the answer to that problem because if we don't know it google does

slope is 35 and 20 miles is the y-intercept.
