Question

Is 1x^2-2x-15=0 a vertical stretch or compression HURRY PLEASE!!

Answer 1

Answer:

NEITHER vertical stretching NOR vertical compression

Step-by-step explanation:

f(x) = 1x^2-2x-15  =  1x^2 - 2x - 15

Because the coefficient of the x^2 term is 1, there is NEITHER vertical stretching NOR vertical compression.

Here f(x) = 1x^2 - 2x - 15 = x^2 - 2x + 1 - 1 - 15  =  (x - 1)^2 - 16

represents a parabola whose vertex is at (1, -16), which opens up, and which has stretching in neither direction (horizontal or vertical).
