can a smart person that is godly at geometry help me answer these four questions please? i will give you a virtual fake dollar and hug :)

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

What is the value of x in the equation7x+2y=48 when y=3

Given: p: 2x = 16 q: 3x – 4= 20 which is the converse of p - q? if 2x + 16, then 3x - 4 20. if 3x –4 +20, then 2x # 16. lf 2x = 16, then 3x - 4 = 20. lf 3x – 4= 20, then 2x = 16. o o
