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 .
