Answer: f(12) = 137, f(-7) = 42
Step-by-step explanation: In a function, what you want to do is plug in the value they give you for x. This means you substitute x with the value they are looking for.
In this case, they are looking at 12 and -7. Let's do 12 first.
The equation becomes (12^2) - 7. 12^2 is 144, and 144-7 is 137.
Now we do -7. The equation becomes (-7)^2 - 7. -7^2 is 49, and 49 - 7 is 42.

Answer:
perimeter=25.12 ft
Area=50.24 ft^2
Step-by-step explanation:
Radius=4 feet
π=3.14
Perimeter=2 x π x Radius
Perimeter=2 x 3.14 x 4
Perimeter=25.12 feet
Area=π x radius x radius
Area=3.14 x 4 x 4
Area=50.24 ft^2
