Question

a bank charges a fee on savings accounts that are inactive for an extended period time. the equation y =7500 (0.97)x represents the value of y, of one account that was left inactive for a period of x years. what is the y-intercept of the equation and what dose it represent?

Answer 1

I assume the function is y =7500 (0.97)^x. The y-intercept is 7500 and it represents when the account is still active or have been inactive for 0 years.

Answer 2

Answer: The y intercept = (0,7500)

It represents the original amount of money in the account before left inactive. = $7,500

Explanation:

Given: A bank charges a fee on savings accounts that are inactive for an extended period time.

The equation
`y =7500(0.97)^x` represents the value of y, of one account that was left inactive for a period of x years.

To find the y intercept , put x=0 in the equation, we get

`y=7500(0.97)^0=7500`

Hence, the y intercept of the given equation = (0,7500)

It represents the amount of money in the account that was left inactive for a period of 0 years.

i.e that is the y intercept represents the original amount of money in the account before left inactive = $7,500
