Question

15 POINTS
how many real zeros does the following quadratic function have?

Answer 1

C.

Explanation:

We check the value of the discriminant, which is

D = b^2 - 4ac

Here it is

16^2 - 4*16*4

= 0.

This value tells us that there one real zero (multiplicity 2).

NOTE:

A positive value of D means there are 2 unique real zeros and a negative there are no real zeros.
