Question

For the function ƒ(x) = 8(x - 3) + 13, find the value of ƒ(5).

Select one:
A. 29
B. 14
C. 36
D. 43

Answer 1

To find the value of $f(x)$ for a given $x$, simply substitute the x-value into the equation for $f(x)$. This will be done as shown:

$f(x) = 8(x - 3) + 13$

$f(5) = 8(5 - 3) + 13$

$f(5) = 16 + 13= 29$

Our answer would be Choice A, or 29.
