What is the inverse of the function f(x) = 2x + 1?
soldier1979 [14.2K]

Answer: The inverse of the linear function f(x)=2x+1 is f^(-1) (x) = (1/2)x-1/2


Solution

f(x)=2x+1

y=f(x)

y=2x+1

Isolating x: Subtracting 1 both sides of the equation:

y-1=2x+1-1

y-1=2x

Multiplying both sides of the equation by 1/2:

(1/2)(y-1)=(1/2)2x

(1/2)y-1/2=x

x=(1/2)y-1/2

Changing "x" by "f^(-1) (x)" and "y" by "x":

f^(-1) (x) = (1/2)x-1/2

What is the answer to: 7(w+2)+0.5w=5
Zepler [3.9K]
First, distribute the 7:

7w + 14 + 0.5w = 5

Combine like terms:

7.5w + 14 = 5

7.5w = -9

Divide both sides by 7.5 to solve for w:

w = -9/7.5 = -1.2

The answer is -1.2
