The function h(x) is a translation of the exponential function g(x) = 2(3)x − 4. What's h(x) if the translation is a vertical stretch by a factor of 2, a vertical shift upward 9 units, and a horizontal shift to the right 7 units? Question 8 options: A) h(x) = 4(3)x + 7 − 9 B) h(x) = 4(3)x – 7 + 7 C) h(x) = 4(3)x − 7 + 9 D) h(x) = 4(3)x − 9 + 7 Question 9 (5 points)
