Given h(x) = -X – 2, solve for x when h(x) = 3.

x = -5

Step-by-step explanation:

One is given a function and the value of the function at a certain output. One must set the function to the given output, and solve to find the input,

h(x) = - x - 2

h(x) = 3

Set the output equal to the input,

h(x) = - x - 2 = 3

Inverse operations,

- x - 2 = 3

    +2    +2

- x = 5

*-1   *-1

x = -5

1/6
