Question

1-Graph y=3x2+24x+45y=3x2+24x+45. State the coordinates of all intercepts and vertex. If you have access to a printer, use a coordinate system printed

2-Use another color to clearly mark all points on the graph P(x,y)P(x,y) with a negative y−y-coordinate.

3- For each point P(x,y)P(x,y) you have marked, mark the point Q(x,0)Q(x,0) with a third color.

4-Express the x−x--coordinates of marked points on the x−x-axis using interval notation.
