Answer:
x = 4.
Step-by-step explanation:
f(2) = 3(2) - 1 = 5.
So 2x - 3 = 5
2x = 5 + 3
x = 8/2 = 4 (answer).
Answer:
g(x) =f(2) when x=4
Step-by-step explanation:
First step is to find f(2)
f(2) is when x=2
f(2) = 3(2) -1
f(2) = 6-1
f(2) = 5
We want to find x when g(x) =5
g(x) = 2x-3
5 = 2x-3
Add 3 to each side
5+3 = 2x-3+3
8 = 2x
Divide each side by 2
8/2 = 2x/2
4 = x
