posted by confusedPlease help!!!! .
Given the following polynomial, find
a. the zerros and the multiplicity of each
b. where the graph crosses or touches the xaxis
c. number of turning points
d. end behavior
f(x)=(x1)(x5)
**please show work**

a). Zeros are at x = 1 and 5.
Multiplicity of each is one.
b). at x=1 and x = 5 is where y = 0
c). f'(x)  0 at turning points (maxima or minima). That occurs when 2x = 6
x = 3.
d). For very large x (positive or negating x), f(x) increases as a parabola upward to infinity.
