Question

For the function h defined by h(x)=2x2−2, find h(−12)

Answer 1

To find h(-12), substitute -12 into the function h(x)=2x²-2. The value of h(-12) is 286.

Step-by-step explanation:

To find h(-12), we substitute -12 into the function h(x)=2x²-2:

h(-12) = 2(-12)² - 2

h(-12) = 2(144) - 2

h(-12) = 288 - 2

h(-12) = 286

Therefore, h(-12) is equal to 286.

Answer 2

Given h(x), we can find for the value of h(-12) by simply substituting x with -12 in the equation. Therefore,

h (x) = 2 x^2 – 2

When x = -12

h (-12) = 2 (-12)^2 – 2

h (-12) = 286 (ANSWER)
