Linear and exponential function transformations: consider the two functions given below. which of the following pairs of transformations causes the graphs of the functions to have the same y-intercept?

For this case we have the following functions:
 f (x) = 3x + 4
 g (x) = 2 ^ x - 1
 The intersection with the y axis of the original functions is:
 f (0) = 3 (0) + 4 = 0 + 4 = 4
 g (0) = 2 ^ 0 - 1 = 1 - 1 = 0
 The transformations that must be applied so that they have the same intersection with the y axis are:
 f (x) - 3
 g (x) + 1
 
 f (x) - 3
 g (x) + 1
