Correct Answer: A

Rationale

Choice A is correct. The value of $h left parenthesis negative 2 right parenthesis$ can be found by substituting $negative 2$ for $x$ in the equation defining $h$ . Substituting $negative 2$ for $x$ in $h (x) = 3 x - 7$ yields $h (- 2) = 3 (- 2) - 7$ , or $h (- 2) = - 13$ . Therefore, the value of $h left parenthesis negative 2 right parenthesis$ is $negative 13$ .

Choice B is incorrect. This is the value of $h left parenthesis negative 1 right parenthesis$ , not $h left parenthesis negative 2 right parenthesis$ .

Choice C is incorrect and may result from conceptual or calculation errors.

Choice D is incorrect and may result from conceptual or calculation errors.
