Answer:
f(-2 ) =2
f(0) = 3
f(4) = -1
Step-by-step explanation:
Clearly by looking at the graph of the given function f(x) we could observe that the function f(x) is increasing in the interval (-∞,0] and then decreasing in the interval (0,∞).
Also, the function is discontinuous at x=0.
( Since, there is a break in a graph and also the left and right hand limit of the function are not equal at x=0)
Hence, from the graph we could directly say that:
f(-2 ) =2
f(0) = 3
f(4) = -1
P(x) = amount made - cost
p(x) = 20x-7x-10
p(x) = 13x -10
Surface area of the cylinder = 1850 square meters
Radius = 9 meters
Surface area of cylinder = 2*pi*r*h
1850=2*22/7*9*h
h = 1850*7/2*22*9
= 32.7 meters
Volume of cylinder = pi*r*r*h
= 22/7*9*9*32.7
= 8324.48 = 8324 (approx) cubic meters
