What is the inverse of the function y - 2 = 3x?

Solution

To find the inverse of the function y2=3xy - 2 = 3x, we follow these steps:

  1. Rewrite the function in terms of yy: y2=3xy - 2 = 3x Add 2 to both sides: y=3x+2y = 3x + 2

  2. Swap xx and yy to find the inverse: x=3y+2x = 3y + 2

  3. Solve for yy (the inverse function): x2=3yx - 2 = 3y Divide both sides by 3: y=x23y = \frac{x - 2}{3}

Thus, the inverse of the function is y=x23y = \frac{x - 2}{3}, which matches option C.

Answer: C y=x23y = \frac{x - 2}{3}
