Input -3 for x
f(-3)=(-3)^2-4(-3)+3
f(-3)=9+12+3
F(-3)=24
A
Parallelogram:
just multiply 16 by 30.
The area is 480.
Semicircles:
Since there are 2 semicircles, they can be merged to one circle.
The area of a circle is πr²
The diameter is 28, so the radius is 14.
Substitute and solve.
π14²
π196 ≈ 615.8
Now add 615.8 with 480
Your answer is 1,095.8 units squared.
For x = 4
7 x 4 + 49 = 77
Answer Is 77
C . Parabola that opens to the left
The distance formula is:
d = √[(x2 - x1)^2 + (y2 - y1)^2]
To use it, you need to have two points on a line that will look like this:
(x1, y1) and (x2 , y2)
Then you just plug it in, and you get your answer.
