Answer:

y = 1/2x +5

Step-by-step explanation:

change f(x) to y

y = 2x - 10

then switch x and y

x = 2y - 10

then solve for y

add 10 to both sides and divide both sides by 2

Answer:

Step-by-step explanation:

One way to find the inverse is:

1.  replace the symbol f(x) with y (for simplicy--stay tuned).  Now you have

  y = 2x -10

2.  switch  x  and  y.  You get  x = 2y - 10

3.  Solve for y.

x + 10 = 2y

y = (x + 10)/2

4.  Replace  y  with the symbol for the inverse function,

Another approach is to think about inverse operations in reverse order.

f(x): start with x

multiply by 2

subtract 10

Inverse: start with x

add 10 (addition is the inverse of subtraction)

divide by 2 (division is the inverse operation of multiplication)
