Explanation:
To find the inverse of an equation, we switch x and y:
x=(12)y+7
And solve for y:
x=(12)y+7 (subtract 7 from both sides)
x7=(12)y (multiply by 7 both sides)
2(x7)=y
y=2x14
To write that this equation is the inverse of the original one, we write the expression as y1=2x14

Solve for y
y=2x+14
Replace y with f1(x) to show the final answer
f1(x)=2x+14
Verify if f1(x)=2x+14 is the inverse of f(x)=(12)x+7
f1(x)=2x+14
