Question

Use the following function rule to find g(7z). Simplify your answer.

g(u)=7u–2

g(7z)=

I do need the process here

Answer 1

just substitute 7z for u in the first equation.. so you get 7(7z)-2 = 49z - 2.

Answer 2

`\sf g(7z) = 49z - 2`.

Explanation:

Given the function rule
`\sf g(u) = 7u - 2`,

To find g(7z) , we need to substitute u = 7z into the function:

`\sf g(7z) = 7(7z) - 2`

Simplify by performing the multiplication:

`\sf g(7z) = 49z - 2`

So,
`\sf g(7z) = 49z - 2`.
