Inverse with variables x and y

The answers are B and D

Step-by-step explanation:

To find the inverse of a function, you have to switch the x and y variables. For example:

Find the inverse of y=2x+3

(1) y=2x+3 (rewrite the equation)

(2) x=2y+3 (switch the variables)

(3) 2y=x-3 (step one of solving for y: subtract 3 from both sides)

(4) y=x/2 -1.5 (step two of solving for y: divide 2 from both sides)

Hence, the inverse of y=2x+3 is y=x/2 -1.5

You would do the same process for each of the ones listed in this question.
