Question

If f(x)=7(x-1)+8, what is the value of f(1)

Answer 1

`\huge f(1) = 8`

Explanation:

`f(x)=7(x-1)+8`

To find f(1), substitute the value of x that's 1 into f(x). That is for every x in f(x) replace it with 1

We have

`f( 1) = 7(1 - 1) + 8 \\ \: \: = 7(0) + 8`

We have the final answer as

`f(1) = 8`

Hope this helps you
