In this question , we have to find, which option represents inverse functions.
Let's check out option b
Let it be y
So we have
Switching x and y and solving for y,
Performing cross multiplication
Combining like terms
Which is same as of the other function.
So correct option is b .
Answer:
B
Step-by-step explanation:
Plug in all the values for x & y into the equation y=2x+3 (B). 2*2=4. 4+3=7. All the other values for x & y match up perfectly as well. The answer is B
