Question

Evaluate the function.
f(x) = -4x2 + 5x
Find f(6)

Answer 1

-114

Explanation:

to evaluate the function f(x) to find f(6) means to substitute x by 6

f(x) = -4x² +5x

f(6) = -4*6² +5*6

f(6) = -144 + 30

f(6) = -114

Answer 2

f(6) = -114

Explanation:

f(x) = -4x² + 5x

f(6) = -4(6)² + 5(6)

f(6) = -4(36) + 30

f(6) = -114 + 30

f(6) = -114
