The function h is defined by h x = 3 x - 7 . What is the value of h

Question

The function h is defined by h x = 3 x - 7 . What is the value of h - 2 ?

Accepted Answer

Choice A is correct. The value of h - 2 can be found by substituting - 2 for x in the equation defining h . Substituting - 2 for x in h x = 3 x - 7 yields h - 2 = 3 - 2 - 7 , or h - 2 = - 13 . Therefore, the value of h - 2 is - 13 . Choice B is incorrect. This is the value of h - 1 , not h - 2 . Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
