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

has an amplitude A, a vertical shift B, a wave number k, and a phase angle . What this all means is that
The function is centered about the line y = B
The function has a vertical span of A above y = B and A below y = B
The function has a wavelength (distance between maxima) of .
The function has been displaced units to the left.
