Keith used the following steps to find the inverse of f, but he thinks he made an error. Step 1. f(x) = 7x + 5 given

Step 2. y = 7x + 5 change f(x) to y

Step 3. x = 7y + 5 switch x and y

Step 4. x + 5 = 7y + 5 add 5 to each side

Step 5. x + 5 = 7y divide each side by 7

Step 6. x + 5/7 = y change y to g(x)

Step 7. g(x) = x + 5/7 switch sides of the equation
