Question

use the following function rule to find f(-31).
f(x) = -3\sqrt{67} + x
f(-31) = \square

Explanation:

Step1: Substitute $x=-31$ into $f(x)$

$f(-31) = -3\sqrt{67 + (-31)}$

Step2: Simplify the radicand

$67 + (-31) = 36$, so $f(-31) = -3\sqrt{36}$

Step3: Calculate the square root

$\sqrt{36}=6$, so $f(-31) = -3\times6$

Step4: Compute the final product

$-3\times6 = -18$

Answer:

$-18$
