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.
Hope this helped!
Answer:
The Area of the parallelogram = 144 m²
Step-by-step explanation:
<u><em>Formula</em></u>:
Area of a parallelogram = b × h
Where , b is the base of the parallelogram
and h is its height.
………………………………
In our case :
b = 12 ; h = 12
Then
The Area of the parallelogram = 12 × 12 = 144 m²
