By evaluating the functions we get:

  • f(3)=  -15
  • f(-2) =  -1
  • g(4) = 23
  • g(-5) = 77
  • g(a) = 3*a^2 - 3*a - 13

How to evaluate a function?

Here we have the two functions:

f(x) = -2x - 5

g(x)= 3x^2 - 3x - 13

And we want to evaluate them in some values of x, first let's do the ones for f(x).

We just replace the variable x by the numbers.

f(3)= -2*3 - 5 = -10 - 5 = -15

f(-2) = -2*(-2) - 5 = 4 - 5 = -1

The ones for the function g(x) are:

g(4) = 3*4^2 -3*4 -13 = 23

g(-5) = 3*(-5)^2 - 3*(-5) - 13 = 77

g(a) = 3*a^2 - 3*a - 13
