Could tutors please help me to understand how to solve the given problem?

Problem: You leave your house in a car. Assume your house is located at the origin. Looking straight down, the road is shaped like the function f(x) = x2 (assume all variables are measured in units of miles here). The odometer in your car says you have traveled a total of 5 miles along the road before stopping the car. If you were to draw a straight line from where you stopped your car to your house, how far away is your house along that straight line
