Directions: Using the digits 1 to 9 at most one time each, fill in the boxes to create a function such that at x = 2, the derivative (at that point) would fall in the interval of {0, 48}

### Hint

One might consider solving the equation at the extremes and means of the interval of solutions

Sometimes small numbers are easier to start with

### Answer

Reading left to right in image one (near largest I believe) solution is: {4, 3}
