    Calculus: Derivatives Problem #2

    because when you plug in -1 for y=2x^3+24x-18 the end result is a negative not positive. The other choices to the questions are: b.decreasing for all values of x c.only increasing for values of x on the interval (-infinity,-2)U(2,+infinity) d.only increasing for values of x on the...
