Answer:
Explanation:
1). f(x) = 5x - 1
Convert the function into the equation,
y = 5x - 1
Substitute 'x' by 'y' and 'y' by 'x',
x = 5y - 1
Solve the equation for y,
y =

So the inverse function is,
Y-intercept of the function is

Therefore, graph (2) is the answer.
2). f(x) =

Inverse of this function will be,

So the line of this function will pass through the origin.
Graph (3) will be the answer.
3). f(x) = x - 5

Graph having y-intercept = 5 will be the answer.
Option (4) will be the graph of the given inverse function.
4). f(x) = 7x + 1
Inverse of this function will be,

Graph with Y-intercept =
(Negative y-intercept) will be the answer.
Option (1) will be the answer.
