Let y = f (x) and g (y) = x

y = (2x + 3) / 5

5y = 2x + 3

x = [ 5y - 3 ] / 2

g (y) = [ 5y - 3 ] / 2

g (x) = [ 5x - 3 ] / 2_____inverse function

Let f(x) = y

Hence

y = (2x + 3) / 5

5y = 2x + 3

2x = 5y - 3

x = (5y- 3) / 2

'Swop' the letters

y = (5x - 3) / 2

f^-1(x) = (5x - 3)/2

Hence second statement is the answer!!!!
