Usually there will be a line through the graph, labeling f(x) = ..... so plug in f(3) and follow the line on the x-axis to look for 3 then find y
Here, you have to determine values of f(x) for negative domain. Domain are those values of x for which function is defined.
Since the function is a polynomial, every value of x∈R is defined for f(x).
And for every negative value of x, f(x) will always be positive because x is squared and square of negative real number is always positive.
0 is neither negative nor positive. Therefore, zero is not included in negative domain. If you plug say x= -0.00000956, f(x) will be greater than 1 because square of x will never be negative.
Thus, the range will always be positive or greater than equal to 1.
Therefore, y≥1

72÷16=4.5
Answer:
4842.24 cubic feet
Step-by-step explanation:
Use the formula for the volume of a cone, V = 
r²
The diameter of the cone is 34 ft, so the radius is 17 ft.
Plug in the radius and height into the formula, and solve for the volume:
V = r²
V = (17)²
V = (289)
V = 4842.24
So, the volume of the cone is 4842.24 cubic feet
