Answer:
Step-by-step explanation:
1) Plug in the number to the equation
f(-11) = |-11 + 8|
= |-3|
absolute value makes it positive so the answer is 3
2) Plug in the number to the equation
f(2) = |2 -5| +3
do the absolute value before adding the 3
|-3| + 3 = 3 + 3
= 6
Answer:
1. f(-11) = 3.
2. f(2) = 6.
Step-by-step explanation:
Note the vertical lines around the x + 8 is the absolute value which is always positive.
f(x) = |x + 8| so f(-11) = |-11 + 8|
= |-3|
= 3 (answer).
If f(x) = |x – 5| + 3, find f(2).
f(2) = | 2 - 5| + 3
= |-3| + 3
= 3 + 3
= 6 (answer)
