Question

If g (x) = 3x²-4, then find g (-3)

Answer 1

g(-3) = 23

Explanation:

This question is telling us that x = -3. Knowing this, we can plug x into the equation and solve to find g(-3).

`g(-3) = 3(-3)^(2) -4`

`g(-3) =3(9)-4` Square -3 to get 9

`g(-3) = 27-4` Multiply 9 by 3 to get 27

`g(-3) = 23` Subtract 4 from 27 to get 23

Thus, g(-3) is equal to 23.

I hope this helps! Good luck!
