Question

Determine (yes or no) whether the given k is zero of f(x)-
f(x) = 3x² +17x +10; k = -15

Answer 1

Answer:

-15 is not a zero of f(x)

Step-by-step explanation:

f(-15) = 3$(-15)^{2}$ + 17(-15) + 10

       =3(225) - 255 + 10 ≠ 0

       = 675 - 255 + 10

       = 430 ≠ 0

-15 is not a zero of f(x)
