The answer is number 1 since a function can't have x repeated. all the other ones have a single x giving 2 numbers. if this happens once it is no longer a function.
Step-by-step explanation:
Assume that

hence,

now,

attached below is the complete solution
Answer:
A
Step-by-step explanation:
A function have the inverse only if it passes the horizontal line test ,
For the given options we need to look for the function which passes the horizontal line test
Option A is g(x)= 2x-3 which is a straight line with slope not equal to 0 so it passes the horizontal line test and hence it will have an inverse which is also a function.
Option B: we need to restrict the domain to get the inverse so the option B is not correct .
Option C : It also fails the horizontal line test .
Option D : Horizontal line so it also fails the horizontal line test .
