Hello, I need help on my Mathematics 30-1 (Pre-calculus) Quiz 7.2 Question #3 and Numerical Response #1

Quiz 7.2 - TS ADINOMURA\\BOIONS LISITIUM .A TAAS Numerical Response The point (-1, 2 ) lies on the graph of y = f(x), which then undergoes a vertical and a 1 . horizontal stretch. The corresponding point on the graph of the transformed function is (-4, 4). What is the vertical stretch factor? Hint: The y-coordinates are affected by a vertical stretch. 3. Which of the following sequences of transformations tell how the graph of y = 4/2x - 6 can be produced from the graph of y = Vx? A . Vertical stretch by a factor of 2, horizontal stretch by a factor of -, horizontal translation 6 units right. B. Vertical stretch by a factor of 4, horizontal stretch by a factor of 2, horizontal translation 3 units left. C. Vertical stretch by a factor of 4, horizontal stretch by a factor of - , horizontal translation 6 units left. D. Vertical stretch by a factor of 4, horizontal stretch by a factor of -, horizontal translation 3 units right. Hint: Compare y = 4/2x - 6 to y = avb(x - h) + k
