Answer:
Step-by-step explanation:
To find g(-3) all we have to do is plug the value of x = -3 into our function g(x)
So we have:
g(x) = -2x + 3x
So every place there is an x in that equation we are gonna put in a -3 because we want g(-3).
So: g(-3) = -2(-3) + 3(-3)
g(-3) = 6 - 9
g(-3) = -3
So we can say that when x = -3
g(-3) = -3
