Step-by-step explanation:
We have the point (1,3) given, the first translation states to move 2 units to the right, or in other words, add 2 to x. out point is now (3,3), the next step is to reflect over the X axis, so we then get the point (3,-3)
we have
using a graph tool
see the attached figure
So
1) the domain of the function is all real numbers-----> interval (-∞,∞)
2) the range of the function is the interval [-1, ∞)
3) the function decrease on the interval (-∞,2)
4) the function increase on the interval (2,∞)
5) the function has two x-intercepts-----> (1,0) and (3,0)
6) the function has one y-intercept-----> (0,1)
therefore
the graph in the attached figure
Answer: 113.1
Step-by-step explanation: v=4/3(pie)r^3=4/3•(pie)•3^3= 113.09734
