Question

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.

Answer 1

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!

Answer 2

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.
