1. domain and range of
A. y = (-4)/(square root of (x + 1)
B. y = square root of (9 + x)
2. A cone is constructed from a circular piece of paper with a 3-inch radius by cutting out a sector of the circle with arc length x. The two edges of the remaining portion are joined together to form a cone with radius r and height h, as shown in the figure. Express the volume V of the cone as a function of x.
3. Determine if the function has an inverse function.
A. y = X^2 + 5x - 3
B. y = x^3 - 3x + 5
y = 2 sin (4x + (pie/3)) + 1
