Answer:
The vertex is (-1, 4), the domain is all real numbers, and the range is y less than 4
Step-by-step explanation:
Given
Solving (a): The vertex;
Assume the general form of a function is
The vertex is determined by
By comparison, we have:
Solve for h, we have:
So, the vertex is:
The domain; x is all real numbers
From the function;
This can be rewritten as:
This implies that:
Whatever the value of is, it will be subtracted from 4 to give y or f(x);
Hence:
y is less than 4

Answer:
A. 63.8 in^2
Step-by-step explanation:
The surface area of a cylinder is given by:
A=2πrh+2πr^2
2πr^2 gives the area of the 2 ends, each with area πr^2.
2πrh gives the suface area of the outside of the cylinder.
r = 0.4 inches
h = 25 inches
Area = 63.8 in^2
