PSAT / NMSQT Question 26 from Practice Test 1 Section 2 Module 2
This is the answer to question 26 from the PSAT / NMSQT Practice Test 1 Section 2 Module 2 Math portion from the College Board website. The question is The functions f and g are defined by the given equations, where x is greater than or equal to 0. Which of the following equations displays, as a constant or coefficient, the maximum value of the function it defines, where x is greater than or equal to 0? I. f(x) = 33(0.4)^(x+3) II. g(x) = 33(0.16)(0.4)^(x-2) This question involves functions, exponential functions, graphing, and identifying the maximums of a function. Calculators ARE allowed on this section. This practice test is provided for free by the College Board. This video will show you how to do this problem and the logic behind it.
