Substituting = 0 for x in this equation yields f^ h 10^ h , or f^ h . Since it′s given that y f^xh, it =- = = follows that y 2 when x 0. Therefore, the y-intercept of the graph of y f^xh in 0,-2 the xy-plane is ^ h. 42 SAT PRACTICE TEST #8 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n MATH: MODULE 2 Choice A is incorrect and may result from conceptual or calculation errors.
