Question

f(x) = 5 – 3x²
x = -1
x = 2
Evaluate f(x) at the given values of x.

Answer 1

when x = -1

f(-1) = 5 - 3(-1)^2

f(-1) = 5 - 3(1)

f(-1) = 5 - 3

when x = 2

f(2) = 5 - 3(2)^2

f(2) = 5 - 3(4)

f(2) = 5 - 12

got it?

Answer 2

Answer 3

what about Evaluate the function f(x) at the given values.
f(x) = 3x² -6
x = -3
x = 2

Answer 4

just substitute
