Question

Given the function f(x)=-3x^2+4x+6 find f(2) and f(3)

Answer 1

f(2)= 2, f(3)= -9

Explanation:

To find f(2) o f(3), you simply plug the respective number into the function, substituting it for x:

f(2)= -3(2)^2 + 4(2) + 6

f(2)= -12 + 8 + 6

f(2)= 2

f(3)= -3(3)^2 + 4(3) + 6

f(3)= -27 + 12 + 6

f(3)= -9
