Question

Use the following function rule to find f(-3).
f(x)=-11-3 |x||

Answer 1

`f(-3) = -20`

Explanation:

f(x)=-11-3 |x|

for f(-3), plug in -3 wherever there is a variable in the equation

`f(-3) = -11 -3|-3|`

The absolute value of -3 is 3

`f(-3) = -11 -3(3)\\f(-3) = -11 - 9\\f(-3) = -20`
