Answer 1

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?

Select each correct answer.



The graph decreases from left to right.

The graph has an x-intercept and a y-intercept.

The point (4, 2.81)(4, 2.81) is on the graph.

The graph has a y-intercept only.

The point ​ (4, 2.62)(4, 2.62) ​ is on the graph.

The graph increases from left to right.

Answer 3

Well--> We know that this is definitely going to be an exponential function looking something like:

Answer 4

Now: using deductive reasoning --> we can clearly see that the graph is increasing from L to R as time passes --> watermelon gets more expensive.

Answer 5

so the last one right?

Answer 6

There will also never be a point on the graph where it crosses the x axis--> true for all exponential increasing functions.

& yep but there is more than one correct answer

Answer 7

second one

Answer 8

We know that there is a y intercept, the graph increases from left to right
& now we have to find what the point is on the graph when x=4

& no...

Answer 9

Basically --> there will never be a time when there is an x intercept because that implies that the watermelon will have a cost that is negative

Answer 10

third or fifth

Answer 11

yep.. so with this question you'll need to recall that ;
