Answer 1

a. vertical compression; `g(x) = 2x^3+x^2-2x+3`

Explanation:

We one multiplies a function by `1/3`, one lowers the y value corresponding to a given x by a factor of `1/3`; this has the effect of vertical compression and the equation for `g(x)` is:

`g(x) = 2x^3+x^2-2x+3`

Answer 2

`a`

Explanation:

`f(x)=y=f(x)`

`g(x)=1/3f(x)`

As you can see in`g(x)` the `y-values` are `1/3` the `y-value` in `f(x)`. That means your `f(x)` was compressed vertically, i.e. it is like someone pressed down on it from the top and squished it to `1/3` the size.
