To solve for f(13), we need to substitute the value of x with 13 in the given function f(x).
Fist, we start with the function:
f(x) = (4x + 1) / 3
Now we replace x with 13:
f(13) = (4(13) + 1) / 3
Next, we calculate the value inside the parentheses:
4(13) = 52
Now, we can add 1:
52 + 1 = 53
Now we substitute back into the equation:
f(13) = 53 / 3
Finally, when we perform the division:
53 / 3 = 17.6667
Thus, the value of f(13) is approximately 17.67.
