Question

Evaluate piecewise functions
Pls answer

Answer 1

-23

Explanation:

x = -5 lies in the last piece

h(-5) = 4(-5) - 3

= -20 - 3

= -23

Answer 2

Explanation:

Step 1: Find which piece-wise function it is in

Equation 1 → x < -7

Let x = -5 → (-5) < -7 ← False

Equation 2 → -7 ≤ x < -5

Let x = -5 → -7 ≤ (-5) < -5 ← False

Equation 3 → x ≥ -5

Let x = -5 → (-5) ≥ -5 ← True

Step 2: Find the value of h(-5)

`h(-5) = 4x - 3`

`h(-5) = 4(-5) - 3`

`h(-5) = -20 - 3`

`h(-5) = -23`

Answer:
`h(-5) = -23`
