The parabola opens downward
Answer:
F(x) = -
Step-by-step explanation:
A square root can only have a positive input for the domain
(The domain is the input for the function)
The cube root can be either negative or positive as an input
F(x) = -
can have inputs from negative infinity to infinity
Answer:

Step-by-step explanation:
Synthetic division is a useful tool for problems of this sort. (see below)

Another way to work this one is to make use of the remainder theorem. The remainder from division by x+2 will be the value of the function at x=-2 (the value of x that makes the divisor be zero).
(-2)³ -7 = -8 -7 = -15
Only one answer choice shows a remainder of -15, and all agree on the quotient.

Here's what the equation would look like:
30(50) + 0.03(4596)
1500 + 137.88
Paige earned $1637.88.
The correct answer is 2/5 because it is the simplest form of 16/40. Hope this helps.
