Question

use the function to answer the question
f(x)=x-7

what is the value of x when f (x)=3

Answer 1

To find the value of \( x \) when \( f(x) = 3 \), we start by setting the function equal to 3:

\[
f(x) = x - 7
\]

We set this equal to 3:

\[
x - 7 = 3
\]

Now, we solve for \( x \):

1. Add 7 to both sides:

\[
x = 3 + 7
\]

2. Simplify:

\[
x = 10
\]

So the value of \( x \) when \( f(x) = 3 \) is \( x = 10 \).
