I need help! Please help do the following questions, thanks!

The graph of y =f(x) is shown below. The number of invariant points when y = f(x) is mapped to y = VI(x) Is f(x) = x + 3x -7 N Determine the solution to 3 = 8-2x + 1, and indicate the restrictions on the variable. Select one: -10 0a. x=12.x2 - 7 Ob x= - 12.x 2 Oc x=-12.x5- Od. x=12.x5 - Ruth solved the equation 8 =x - VX -6 as follows B = x-VX-6 3-x = -VX-6 x -8 = \\ x-6 x2-16x +64 = x-6 x2-17x +70 = 0 (x-7)(x-10) = 0 x = 7, 10 The extraneous root(s) introduced by Ruth is/are Select one: O a. 7 and 10 The time, [ seconds, it takes a pendulum to complete one back and forth swing can be determined by the equation t = 0.32JI, where / is the length of O b. no extraneous root was introduced the pendulum in inches. Oc. 10 A clock manufacturer has an adjustable length pendulum with the shortest length being 7 in and the longest length being 11.5 in. Determine the range of O d. 7 swinging times for this pendulum. Select one: me, t seconds, it takes a pendulum to complete one back and forth swing swing can be determined by the equation ( = 0.32/T, where ! is the length of O a. 0.320 St S 1.085 the pendulum in inches. O b. 0.966 st S 1.085 Determine the length of the pendulum if it takes 1.2 s to make a complete back and forth swing. O c 0.847 st s 1.085 Select one: O a. 3.75 in O d. 0.847 St 5 0.966 Ob. 14.06 In Oc 1.94 In O d. 1.89 In The function y = f(x) has a range of (-4,9]. The minimum value of y = JIG) is IF 5/(1) = 20, then the point (1,y) on the graph of y = VIWxy has a y-value of
