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</p>","correct_answer":["D"],"has_media":false,"has_mathml":false,"has_table":false,"source_created_at":null,"source_updated_at":null,"options":[{"label":"A","content_html":"<p>Tavon will keep the vine plant for 9 months.</p>","ord":0},{"label":"B","content_html":"<p>The vine plant is expected to grow 9 inches each month.</p>","ord":1},{"label":"C","content_html":"<p>The vine plant is expected to grow to a maximum length of 9 inches.</p>","ord":2},{"label":"D","content_html":"<p>The estimated length of the vine plant was 9 inches when Tavon purchased it.</p>","ord":3}],"attribution":{"source_id":"cb_practice_pdf","source_name":"College Board full-length SAT practice tests (PDF)","rights_holder":"College Board","canonical_url":"https://satsuite.collegeboard.org/practice/practice-tests/paper","retrieved_from":"https://satsuite.collegeboard.org/practice/practice-tests/paper","attribution":"Full-length SAT practice tests 4–11 © College Board, published free at satsuite.collegeboard.org.","disclaimer":"Extracted from PDF layout: equations, figures and tables do not survive intact.
