Given the function:
f(x) = 7x - ½
Find the inverse of the function:
Solution.
In order to find the inverse of the function, simply equate the solution with y, then change the position of x with y.
y= 7x -½
x=7y- ½
Transpose -½ on the other side of the equation. Note that when transposing a number, the sign changes.
x=7y- ½
x + ½ =7y
Divide both sides by 7 in order to get the value of the inverse function.
y=( x + ½)/7
