Step-by-step explanation:
It is given that,
Sam opened a savings account with a deposit of $50. Every month after that, he deposited $20 more.
It is not a proportional relationship. As initial amount was $50 and every month he deposited $20 more. The ratio is not constant for the deposited amounts.
To make the relationship proportional, he must start with zero balance and then should have deposited $20 every month.
Answer:
Option B:
Step-by-step explanation:
To obtain the inverse of the function , you need to solve the equation for the variable "x":
Now you need to exchange the variable "x" with the variable "y". Then:
Finally, you get that the inverse of the function is:
This matches with the option B.
