Some banks charge a fee on savings accounts that are left inactive
for an extended period of time. The equation y = 5000(0.98),
represents the value, y, of one account that was left inactive for a
period of x years.
What is the y-intercept of this equation and what does it represent?

(1) 0.98, the percent of money in the account initially

(2) 0.98, the percent of money in the account after x years

(3) 5000, the amount of money in the account initially

(4) 5000, the amount of money in the account after a years

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
