For the function f (x) = |x| + 1, find the value when x = - 3

Steps to solve:

f (x) = |x| + 1; x = - 3

~Substitute

f (-3) = |-3| + 1

When you take the absolute value of a number it changes it to a positive number regarding it sign.

~Take the absolute value of - 3

f (-3) = 3 + 1

~Simplify

f (-3) = 4

Best of Luck!
