Find the inverse of f(x)=2x-1
2 answers:
Let's find the inverse of given function ~
[ now, replace f(x) and x with ]
That's the required inverse function ~
Answer:
Step-by-step explanation:
The inverse of a function is denoted by f
To find the inverse of
Set
So
Express x in terms of y
So inverse is
Replace y with x to make it a function of x
To test if this correct, note that the property of an inverse function is that it undoes the original function. In other words if we have f(a) = k then f⁻¹(k) = a
Let's test this with some reasonable value for x
f(2 ) = 2.2 - 1 = 3
f⁻¹(3 ) = (3+1)/2 = 2
Hence correct

Answer:
x = 0
x = 7/5
x = -2/3
Step-by-step explanation:
x2 =0
x=0
5x -7 =0
5x = 7
x = 7/5
3x+2 =0
3x = -2
x = -2/3
These are all the 3 roots of this equation
