 (h) amplitude,
 (i) period,
 (j) vertical shift,
 (k) phase shift,
 (l) domain,
 (m) range.
 (n) Can f(t)=2? Explain.
 Simplify each expression:
 Given that and
, find the remaining five trigonometric functions
of the angle .
 Find if . Restrict
domain if necessary.
 Find the inverse of the following function(restrict the domain
if necessary):
 If you invested $1,000 for 4 years as follows:
 Years 1 and 2 compounded weekly at 11%,
 Years 3 and 4 continuously at 13%,
 What simple interest rate would give you the same balance as the
above after four years?
 Find a polynomial function that passes through the point (3,24),
has a double zero of 3 and zeros 1 and 1
 Of degree 3.
 Of degree 4.
 Of degree 6.
 Solve for x:
 Find the quadratic function whose graph contains
the points (1,2),(2,1) and (1,10).
 Suppose you are given a polynomial function of degree four with
a relative maximum of 10 located at x=0, a relative maximum of 22
located at x=10, and a relative maximum of 5 located at x=4. On
what interval(s) is the function:
 Increasing?
 Decreasing?
 Give two intervals where at least one of the zeros of the
polynomial exists.
