Answer:
The profit function would be p(x) = 7x - 20
Step-by-step explanation:
In order to find this, start by listing just as asked.
p(x) = r(x) - c(x)
Now input the functions where indicated
p(x) = 12x - (5x + 20)
p(x) = 12x - 5x - 20
p(x) = 7x - 20
Answer:
a=-16, b=11, c=23
Step-by-step explanation:
The function that represents the table is

We substitute x=-5 to find the value of a.

We evaluate to obtain:

To find the value of b, we substitute x=4,
We get:

To find c, we plug in x=8,
