Answer:
B
Step-by-step explanation:
To evaluate f(2) substitute x = 2 into f(x), that is
f(2) = - (2)³ + 2(2)² - 3 = - 8 +2(4) - 3 = - 8 + 8 - 3 = - 3

I don't know if this helps but there is an app call symbols which is free which maybe it can help you to grapgh.
Answer: (5, 12)
Step-by-step explanation:
Just graph the linear equations and find where they intersect.
Algebraically, you can set them equal to each other
-3x-3=2x+2
-x-3=2
-x=5
x=5
Plug x=5 to any equation
y=2(5)+2
y=12
The area of the base (six triangles with a base 15m and a height 7.5√3m):
The area of side walls (six triangles with a base 15m and a height 12m)
The surface area:
