Explanation of the answer:
<span>The equation that represents the number of belts sold = 3^x ⇒⇒⇒ blue graph
</span>
<span>The equation that represents the number of wallets sold = 4x+15 ⇒⇒⇒ red graph
</span>
The point of intersection represents <span>the total number of belts sold will be the same as the total number of wallets sold.</span>

Answer:
The positive graph is on the points (-5,-4) and (2,5)
And, negative would be (-4,2)
Step-by-step explanation:
As it seems that fgraph shows positive in the case when it is over x-axis, and negative when it is below y-axis
As on the interval (-1,5)
The graph is below x-axis i.e. on (-1,2)
And, over x-axis i.e. on (2,5)
At this point Lonzell’s is not correct
As on the interval (-5,-1)
The graph is below x-axis i.e. on (-4,-1)
And, over x-axis i.e. on (-5,4)
At this point Lonzell’s is not correct
So,
The positive graph is on the points (-5,-4) and (2,5)
And, negative would be (-4,2)
