I'm having trouble with this question.

The number of horse-power H required to overcome wind drag on a certain automobile is approximated by: H(x)= 0.002(x)^2 + 0.005(x) - 0.029, [10 is less then/equal to (x) is less then/equal to 100].

Where x is the speed of the car in miles per hour.

Rewrite the power function so that x represents the speed in kilometers per hour. [Find H(x/1.6)]. Identify the type of transformation applied to the graph of the power function.
