Did I do this right?
(give me proof)

The polynomial function of least degree with a leading coefficient of 1 is: f(x) = x3 + ax2 + bx + c

If the table of the function contains exactly two potential turning points, one with an input value of –1, which statement best describes all possible values of m? m ≥ –12 –12 < m < 4 m ≤ 4 m ≥ 4 or m ≤ –12

Select the point that is a solution to the system of inequalities. y< =-x+3 y=x^(2)-3x
