An investor invests $500 in a certain stock. after the first six months, the value if the stock has increased at a rate of $20 per month. sketch a graph that represents the situation.

We know that:

Based on this, we can make a table and then graph. x variable is gonna be months, and y variable is gonna be the money. We just need to write six months, and each month increase $20. The initial condition is x=0, in this moment, the money is $500.

x      y

0     500

1      520

2     540

3     560

4     580

5     600

6     620

Remember that each pair represents a point to graph the function.

step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
