use the function to answer the question

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 \( x = 10 \).
