1. domain and range of

A. y = (-4)/(square root of (x + 1)

and

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

and

B. y = x^3 - 3x + 5

4. Graph

y = 2 sin (4x + (pie/3)) + 1
