Answer:
Last Graph (4th one)
Step-by-step explanation:
The equation given is
Since we want increase of 25%, the value of b would be 1.25, so we have:
The graph should be increasing so we can immediately eliminate 2nd and 3rd graphs since they are clearly decreasing. We now have to choose between 1st graph and 4th graph.
<u>1st graph:</u>
Let's take the point (-20,30)
<u>2nd graph:</u>
Let's take the point (-20,4.5)
hence, this makes sense. So the correct graph is 4th one.
