Choose the function for the graph below.
- f(x) = 3x2
- f(x) = -\(\small\mathsf{ \frac{1}{3} }\)x2
- f(x) = -3x2
- f(x) = \(\small\mathsf{ \frac{1}{3} }\)x2
The graph points up so we know that it is positive, but the graph with a>1 will be more narrow.
This graph would point down because its a-value is negative.
This graph would point down because its a-value is negative.
Correct!

This graph would point down because its a-value is negative.
This graph would be wider because a<1.

This graph would point up because its a-value is positive.
This graph would be wider because the a-value is less than one.
