What effect does a in ax^2 have on a graph of a porabola

Asquare and an equilateral triangle have the same perimeter. each side the triangle is 4 inches longer than each side of the square. what is the perimeter of the square

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2

Determine the function’s value when x = -1 a. g(-1)=-3 b. g(-1)=0 c. g(-1)=1 d. g(-1)=27
