Given the following polynomial find,

a. zeros and the multiplicity of each
b. number of turning points
c. end behavior

f(x)=(x-1)(x-5)

a. the multiplicity of (x-1)(x-5)
x=1 and x=5----is this correct

b. number of turning points
I had f(x)-0 at turning points BUT my teacher said note that the equation is a degree of two. f(x)=x^2-6x+5; how many turning points must an equation have that is of degree two?

c. end behavior
I had a large |x|(positive or negative) f(x)increases as a parabola upward to ionfinity. **My teacher said not ot change to an absolute value; so now I am really confused. Can someone help me please?

**please show work**
