8. The vertical and horizontal asymptotes of the graph of y = - A. x =- 2 and y =- 5 x + 2 5, respectively, are B. x =- 2 and y = 5 C. D. x = 2 and y =- 5 x = 2 and y = 5 Hint: A vertical asymptote occurs at an x-value for which a function is undefined and a horizontal asymptote occurs at a y-value for which a function is undefined. 9. The domain of y = 5/(3x + 12) + 3, where /(x) = 4. tip, A. *#-4 B. *#-3 al C. x#-2 D. x70 Hint: A non-permissible value, which is a restriction on the domain, exists when the denominator is equal to zero. 10. An equivalent equation to y = 3.5(2) is A. t = 5log:(3.5) B. 1 = log: (2y) tel out of allgu c riging er phustanat hardt brig . & to C. = 5 log: (y) pant pririotents .e rigsig off! unitsoffer D. 1 = log: (5y) trell norit bas . to Hint: Isolate the power, and then convert to a logarithm. 11. The graph of the inverse, y = f (x), of f(x) = 2" + 2 has a domain of A. * > 0 and no x-intercept B. x > 2 and no x-intercept C. x > 2 and an x-intercept of 3 . x > 0 and an x-intercept of 3 Hint: Recall for the inverse, the x- and y-values are switched
