Question

7. f(x) = 3x - 5 and g(x) = x - 2, What is f(x) o g(x)

e. 3x – 11
g. 3x2 - 11x + 10
f. 3x - 7
h. 3x - 1

Answer 1

Answer:
`3x - 11`

Explanation:

Given :

`f(x) = 3x - 5`

`g(x) = x - 2`

to find
`f(x)` o
`g(x)` , we will first substitute g(x) , that is

`f(x-2)`

The next thing is to substitute
`x-2` in place of
`x` in the value of f(x) , that is

`f(x)` o
`g(x)` =
`3(x-2) - 5`

`f(x)` o
`g(x)` =
`3x - 6 - 5`

`f(x)` o
`g(x)` =
`3x - 11`
