The quadratic functions f(x) and g(x) are described as follows:

f(x) = −2x2 + 9

x g(x)
0 −5
1 3
2 11
3 3
4 −5

Which statement best compares the maximum value of the 2 functions?

retireed · Answer

Plot them both on the same graph to determine the answer.

alliekat01 · Answer

I plotted the function but I'm not completely sure how to plot the table onto a graph

retireed · Answer

The table is easier to plot, since they give you each point of x and y.

alliekat01 · Answer

Okay so do I add plot those points onto my graph for my function? And do I have to pick specific points to plot or do I just pick a set of them from the table

angelica · Answer

Yes, I think you have to plot those points.

alliekat01 · Answer

Okay I plotted it, now what do I do with it?

alliekat01 · Answer

The maximums of the function would be (0,9) and for the table it would be (2, 11) right?

retireed · Answer

Yes

Okie dokie thank you!

angelica · Answer

Hey, you got it! Great.

retireed · Answer

You did it by yourself good job.  I just pointed you towards what you know how to do.
