Question

Evaluate h(x)=-2x+9 when x=-2,0, and 5 .

h(-2)=


h(0)=


h (5)=

Answer 1

The answer is 13, 9 and (-1)

Explanation:

Given;

• h(x) = (-2x + 9)

To Find;

• h(x) = (-2x + 9) when x = (-2), 0 and 5.

For x = (-2)

h(x) = (-2x + 9)

h(-2) = [-2(-2) + 9]

h(-2) = (4 + 9)

h(-2) = 13

For x = 0

h(x) = (-2x + 9)

h(0) = [-2(0) + 9]

h(0) = (0 + 9)

h(0) = 9

For x = 5

h(x) = (-2x + 9)

h(5) = [-2(5) + 9]

h(5) = [(-10) + 9]

h(5) = (-1)

Thus, The answer is 13, 9 and (-1) when x = (-2), 0 and 5 respectively.
