How do you solve for f(13) in the function f(x) = (x – 5) / 3?

To solve for f(13) in the function f(x) = (x – 5) / 3, we start by substituting the value of 13 in place of x.

This gives us:

f(13) = (13 – 5) / 3

Next, we perform the arithmetic inside the parentheses:

13 – 5 = 8

Now our function looks like this:

f(13) = 8 / 3

Finally, we divide 8 by 3:

f(13) = 2.6667 (or 2 2/3 if you prefer fractional form).

Therefore, the final answer is:

f(13) ≈ 2.67
