Alisa buys a watermelon every year. The first time she bought a watermelon, it cost $2.50. She notices the price is getting more expensive, at a rate of 3% per year. Alisa sketches a graph of the situation, labeling the y-intercept and the point representing the price in Year 4. Which statements are true?

The point ​ (4, 2.62)(4, 2.62) ​ is on the graph.The graph decreases from left to right.The point  (4, 2.81)(4, 2.81)   is on the graph.The graph has an x-intercept and a y-intercept.The graph has a y-intercept only.The graph increases from left to right.

The correct answers are the graph has a y-intercept only, the point  (4, 2.81) is on the graph, and the graph increases from left to right. Hope this helps!

This is the exponential function:
y = 2.50 * 1.03^x
For x = 4:
f ( 4 ) = 2.50 * 1.03^4 = 2.50 * 1.1255 = 2.81
Answer:
- The point ( 4, 2.81 ) is on the graph.
- The graph has a y- intercept only.
- The graph increases from left to right.
