Step-by-step explanation:
We need to find the value of the function at the indicated value.

Indicated values are : f(-7), f(0), f(6), f(7)
To find f(-7), put x = -7 in the given function

To find f(0), put x = 0 in the given function

To find f(6), put x = 6 in the given function

To find f(7), put x = 7 in the given function

Hence, this is the required solution.

Answer:
one solution
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
Answer:
$0.38
Step-by-step explanation:
First we need to convert pounds to ounces
1 pound = 16 ounces
Thus 16 ounces cost $3
If a portion requires two ounces of butter, we must find out the cost of these 2 ounces, knowing that 16 ounces cost $ 3
ounces cost
16 -- $3
2 -- x
To find the cost x:

rounding to the nearest cent: $0.38
