Question

Given f(x) = 3x- and g(x) =2x-3 for which value of c does g(x) = f(2)

Answer 1

f(2)=6
6=2x-3
9=2x
x=9/2

Answer 2

x =
`(9)/(2)` is the answer.

Explanation:

Here f(x) = 3x

and f(2) means value of f(x) at x=2

that is

3(2) = 6

here it is given that g(x) = f(2)

2x-3 = 6

2x = 3+6

2x = 9

x =
`(9)/(2)`
