Answer 7

For #8, yes it flips, and in mathematical terms it is called "reflection across the x-axis"

Answer 8

#10, you left out the fact that it is streched by a scale factor of a>1
(you will get that when you factor out of 2 from the parenthesis - which you apparently did)

Answer 9

Please redo #11.

Answer 10

#12 is correct.

(#13 & #14 are not yet completed.)

Answer 11

How do I do #11? & yes any of the ones not answered I need help with.

Answer 12

\(\large\color{black}{ \displaystyle y=2\left(\frac{1}{2}(x+2)\right)^2-7 }\)

you know that:
\(\large\color{blue}{ \displaystyle \left(a\times b\right)^n=a^n\times b^n }\)

and by that rule, you get:

\(\large\color{black}{ \displaystyle y=2\left(\frac{1}{2}\right)^2\left(x+2\right)^2-7 }\)

which simplies to:

\(\large\color{black}{ \displaystyle y=2\left(\frac{1}{4}\right)\left(x+2\right)^2-7 }\)

\(\large\color{black}{ \displaystyle y=\frac{1}{2}\left(x+2\right)^2-7 }\)

Answer 13

then you tell me how to describe this function in terms of the parent function.
