Hello, I need help on my Mathematics 30-1 (Pre-Calculus) Questions #1-#2 and Numerical Response #1

Mathematics 30-1 Quiz 3.1 - TS Value 10 PART A: MULTIPLE CHOICE/NUMERICAL RESPONSE This quiz includes multiple choice and numerical response questions. For multiple choice questions, select the best answer. For numerical response questions, enter the numerical values into the space provided. 1 . The transformation of y = f(x) to y = f( 4x) is a A horizontal stretch by a factor of B. horizontal stretch by a factor of 4 C. vertical stretch by a factor of D. vertical stretch by a factor of 4 Hint: The factor is applied to the x-variable of the function. 2. Compared to the function y = f(x), the function y =- 5f(x) can be described as the result of a reflection in the A. x-axis with a vertical stretch by a factor of 5 B. y-axis with a vertical stretch by a factor of 5 C. x-axis with a horizontal stretch by a factor of 5 D. y-axis with a horizontal stretch by a factor of 5 Hint: All the y-values of the function are affected by a negative factor applied to the entire function. Numerical Response 1. If the point (1, 2) lies on the graph of y = f(x), then the y-coordinate of the corresponding point on the graph of the transformed function y = 2f(4x) is Hint: Focus only on the factor that will affect the y-values of the function. The factor that
