Answer:

Given function: f(x) = |x + 2| - 3

f(x) = 5

⇒ |x + 2| - 3 = 5

⇒ |x + 2| = 8

Two solutions:

Solution 1

⇒ (x + 2) = 8

⇒ x = 6

Solution 2

⇒ -(x + 2) = 8

⇒ -x - 2 = 8

⇒ x = -10

x = 3

⇒ |3 + 2| - 3

⇒ |5| - 3

⇒ 5 - 3 = 2

x = -3

⇒ |-3 + 2| - 3

⇒ |-1| - 3

⇒ 1 - 3 = -2

f(x) = 10

⇒ |x + 2| - 3 = 10

⇒ |x + 2| = 13

Two solutions:

Solution 1

⇒ (x + 2) = 13

⇒ x = 11

Solution 2

⇒ -(x + 2) = 13

⇒ -x - 2 = 13

⇒ x = -15
