The values produced by the function

will not be any lower than -7, but may be that low when x=-3.
That is, the range is
... f(x) ≥ -7 . . . . matches the 1st selection
For this case we have the following functions:

We must find the product of the functions:

We apply distributive property:

Finally, the product of the functions is:
