Step-by-step explanation:
h(- 4) means what is the value of h(x) when x = - 4
Now x = - 4 ≠ 2, thus
h(- 4)
= - × (- 4)² + 4
= - × 16 + 4
= - + = -
h(2) means what is the value of h(x) when x = 2, thus
h(2) = - 2
h(5) means what is the value of h(x) when x = 5
Now x = 5 ≠ 2, thus
h(5)
= - × 5² + 4
=- × 25 + 4
= - + =-
