They are multiplying by two .
Answer:
Below in bold.
Step-by-step explanation:
The zeroes ( = x-intercepts) are x = -3 and x = -1.
So the x -coordinate of the vertex is between x = -3 and x = -1.
The actual x-coordinate is halfway between these value: at x = -2.
Answer: c
Step-by-step explanation:
if the output is 4, a has to be somewhere at y=4
{-4.5,-2,1} are all possible
so c, {-2,1}
Exponential notation allows the representation of numbers in shorter form.
(2 x 2 x 2)(4x4x4) = 2x2x2x2x2x2x2x2x2
