= 14t+9 The function f^-^-^-^-^~ defined by f t gives the estimated length, in inches, of a vine plant t months after Tavon purchased it. Which of the following is the best interpretation of 9 in this context?
Correct answer: D (parsed from the explanation — this source omits an answer key for this item)
Explanation
=14 +9 Choice D is correct. It’s given that the function f defined by f^th t gives the estimated length, in inches, of a vine plant t months after Tavon purchased it. = + For a function defined by an equation of the form f^th mt b, where m and b are constants, b represents the value of f^0h, or the value of f^th when the value =14 +9 of t is 0. Therefore, for the function defined by f^th t , 9 represents the value of f^th when the value of t is 0. This means that 0 months after the vine plant was purchased, the estimated length of the vine plant was 9 inches. Therefore, the best interpretation of 9 in this context is the estimated length of the vine plant was 9 inches when Tavon purchased it. Choice A is incorrect and may result from conceptual or calculation errors. 14 Choice B is incorrect. The vine plant is expected to grow inches, not 9 inches, each month. Choice C is incorrect and may result from conceptual or calculation errors. 46 SAT PRACTICE TEST #6 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n MATH: MODULE 2
