Which graph matches the equationy = tan(3x) - 2? O x 0.5m O * 0.577 O 2.5 -0.5Tt x 0.51 O jobn x 0.57D Question 14 4.5 pts Which is the sine function for the graph below? 2 y - 1 - 2 O y = sin(2x) O y = 2 sin(2x) O y = 2 sin(ac) O y = 2sin (x)Question 15 4.5 pts How is the function g(x) = 3 cos(:r) 1 transformed from the parent cosine function, f(ac) = cos(:r:)? O The midline of f(x) is shifted down by 1 and the amplitude is tripled to create g(x). O The midline of f(x) is shifted up by 1 to create g(x). O The midline of f(x) is shifted up by 3 and the graph is ipped over the x-axis to create g(x). O The midline of f(x) is shifted up by 1 and the period is tripled to create g(x). Question 18 4.5 pts Which function has the longer period? at) 2 3sin(4zc) + 1 g(m) = 2sin(%a:) 2 L 0 f(x) because it has a period of 271' while g(x) has a period of 27f. 0 f(x) because it has a period of4 while g(x) has a period of i. O g(x) because it has a period of 87rwhi|e f(X) has a period of g. Q g(x) because it has a period of 47rwhile f(x) has a period of %. 5 pts D Question 21 What is the period of the function f (x) = tan ( x) - 1? O CT J IA O 2 O O
