Question

Help, Im stuck....

I cannot remember what to do.

(x+6)(x-7)(x+4)>0

The solution set is....{x, }

Thank you:)

Answer 1

The function changes sign at x = -6, 7 and -4.

It is positive only where all three terms are positive (x > 7) , or where one factor term is positive and two are negative (-6 < x < -4)

Put that into set terminology.
