Answer:
The first option ,f^-1(x)=1/2*x-1/2
Step-by-step explanation:
f(x)=2x+1
y=2x+1
Interchanging the places of x and y, we get,
x=2y+1
(x-1)/2=y
f^-1(x)=(x-1)/2
f^-1(x)=1/2*x-1/2
The first option.
Step-by-step explanation:
Replace the sec equation on the first one... Find the value of y first.. And then name the value of y as the third equation.. Replace the third equation on the sec one to get the value of x
