Question

Which function is the result of vertically shrinking f(x) = (x + 1)² by a factor of 1/63

OA) f(x) = (6x + 1)²
.
OB) f(x) = ¹/(x + 1)2
OC) f(x)=(²¹/6x + 1)²
D) f(x) = 6(x + 1)²

Answer 1

Answer: Choice B

Reason:

The 1/6 out front will make the old y output of (x+1)^2 to be 1/6 as high compared to before. For example, if the old output was 42, then the new output is (1/6)*42 = 7. Doing this to every point on the parabola will make it squish down. The 2 in choice B should be an exponent.
