Graph the following function on a separate coordinate plane:
y = –3x2 – 6x – 5
The vertex is (-1,-2). The y-intercept is (0, -5). Based upon the feedback I received, what is the The fourth quadratic function that should be graphed for accuracy to match the labels designated?

The only points on my graph are the vertex and the y-intercept (there is not an x-intercept because there is no real root).

anonymous · Answer

you can add another point by choosing random value of x or y
for example, if x=1 , then y = -3(1)-6(1)-5= -14 
so you have another point : (1,-14)
