given the following function find,
a. zeros and the multiplicity of each
b. number of turning points
c. end behavior
f(x)=(x1)(x5)
a. x=1 and x=5is this correct?
b. number of turning points
I had f(x)0 BUT my teacher said this
Note that the equation has a degree of 2. f(x)=x^26x+5. How many turning points must an equation have that is of degree two? Is it two points(1,0)and (5,0)
c. end behavior
I had for a large x(positiveor negative) f(x) increases as parabola upward to infinity BUT my teacher said not to change to an absolute value. Can someone help me with this one.
**please show work**

Your function is a simple parabola
All parabolas have one turning point, called the vertex
because of the + understood in front of
f(x) = +x^2 ....
the parabola opens upwards so it rises to infinity in both the 1st and 2nd quadrants.
If the function had been
f(x) = x^2 .... , then it would have opened downwards. Your teacher was right to object to the x , that would always make the sign in front a +
Your zeros of x=1 and x=5 are correct, their multiplicity is 1
