I have a screenshot attached.

What is the average rate of change for this function for the interval from x=2 to x=4 ?

What is the multiple zero and multiplicity of f(x) = (x ? 3)(x ? 3)(x + 5)? multiple zero is 3; multiplicity is 2 multiple zero is 5; multiplicity is 1 multiple zero is ? 5; multiplicity is 1 multiple zero is ? 3; multiplicity is 2

What is the slope of the line that contains the points (-2,1) and (0,-3)
