Ben has $5. in order to have money for a new tablet computer, ben is going to sell his collection of stamps for $3 per stamp. ben has decided to graph a line showing the relationship between the number of stamps he sells and the total amount of money he has. which will be the y-intercept of ben's graph?

The y-intercept of Ben's graph is .

Step-by-step explanation:

The function for Ben's amount of money y, depending on the number of stamps sold x, is as follows:

In which a is the price of each stamp and b is his initial money.

Building the function:

Ben has $5. This means that if he sells no stamps, he is still going to have $5. So .

For each stamp sold, he gains $3. So if sells 1 stamp, he will have $8, if he sells 2, he will have $11. So .

The function is:

Which will be the y-intercept of Ben's graph?

This is the value of y when x = 0.

So

The y-intercept of Ben's graph is .

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

2x^2+5x+17

your welcome. : )
