It is a cap-size parabola. The parabola "goes down". The graph of this function looks like in this attached picture.
I think its (<span><span>x^2)</span>+<span>5x</span></span>+<span>49</span>
12x > 9(2x-3)-15
distribute the 9
12x > 18x-27 -15
combine like terms on the right side
12x > 18x-42
subtract 18x from both sides
-6x > -42
divide both sides by -6
x = -42 / -6 = 7
x >7
128 = 128 cause u add them
