Name:
Good luck! Be sure to do all the pages! (36 points total)
True or False. Circle “T” if the statement is always true. (Always!)
Otherwise, circle “F”. (2 points each, 12 points total)
1. T F If −3 is a root of the polynomial function then x+ 3
is a factor of the polynomial.
2. T F 4x+y2= 8 defines yas a function of x.
3. T F If fis an odd function and the point (2,−3) is on
the graph of fthen the point (−2,3) is on the graph of f.
4. T F The function f(x) = x
|x|+2x4is an odd function.
5. T F (f◦g)(x) = (g◦f)(x) for all functions f(x) and
g(x).
6. T F 3x9y= 3x+2yfor all xand y.
