PRECALCULUS Final Study Questions and Answers All Correct

PRECALCULUS Final Study Questions and Answers All Correct Consider the inverse function. f^-1(x)= -|x-2 Which conclusions can be drawn about f(x) = x2 + 2? Select three options. - Answer-f(x) has a limited range. f(x) has a restricted domain. f(x) has a y-intercept at the point (0, 2). The inequality 10x ≤ -0.6x + 7 can be broken into two related inequalities. Review the graphs of the two related inequalities. What is the least integer value in the solution set of the inequality? - Answer--3 For the function q(x) =10x ^5|x-2, what is the inverse function? - Answer-q-1(x) =(x/10)^5+2 Randy and Trey take turns cleaning offices on the weekends. It takes Randy at most 4 hours to clean the offices. It takes Trey at most 6 hours to clean the offices. What is the greatest amount of time it would take them to clean the offices together? - Answer-2.4 hours Consider the function represented in the table. Which point of the given function corresponds with the minimum value of its inverse function? - Answer-A (-20, 8) Suppose f(x) = (5 - x)3 and, g(x) = a + x2, and f(g(x)) = (1 - x2)3. What is the value of a? - Answer-a = 4 One brand of vinegar has a pH of 4.5. Another brand has a pH of 5.0. The equation for the pH of a substance is pH = -log[H+], where H+ is the concentration of hydrogen ions. What is the approximate difference in the concentration of hydrogen ions between the two brands of vinegar? - Answer-2.2x10^-5 Which statement comparing the oblique asymptotes of the functions f(x) and g(x) is true? f(x)=x^2+x+1/6(x-4) The oblique asymptote for g(x) is steeper than for f(x). Both functions have the same oblique asymptote. The oblique asymptote for f(x) is steeper than for g(x). Both functions have parallel oblique asymptotes. - Answer-The oblique asymptote for f(x) is steeper than for g(x).
