Step-by-step explanation:
Inverse function defined as the the function that undergoes the action of the other function.
A function is the inverse of f if whenever y =f(x) and
To find the inverse of the function:
Q1.
Given the function: f(x) = 7x -1
Put y for f(x) and solve for x;
y= 7x -1
Add 1 both sides we get;
y + 1 = 7x
Divide both sides by 7 we get;
Put for x;
Interchange y =x, we have
Q 2.
Given the function:
Put y for f(x) and solve for x;
Add 7 both sides we get;
taking cube root both sides we get
Put for x;
Interchange y =x, we have
Q3 .
Given the function:
Put y for f(x) and solve for x;
Add 3 both sides we get;
Divide both sides by 5 we get;
taking cube root both sides we get
Put for x;
Interchange y =x, we have
