Hello, I need help on Mathematics 30-1 (Pre-calculus) Questions #6 and numerical response #3

Mathematics 30-1 Quiz 3.2 - TS 6. The domain of y = 5f(4x - 8) + 3, where f(x) = _, is A. x # 3 B. x #2 C. x # 0 D. x #- 8 Hint: Determine the equation of the transformed function, and look for non-permissible values. Numerical Response 3. The graph of a sinusoidal function y = asinb(x - c) + d has a minimum point at (-4, - 3) and a subsequent maximum point at (, 5 ). The values of a, b, c, and d, respectively, are Hint: The maximum and minimum y-values can be used to determine both the amplitude and the vertical displacement. Then, determine if there was a phase shift. Next, determine the value of b. Recall that period = 27 b
