Answer:
y = -5x³
Step-by-step explanation:
The point of inflection of the parent cubic function f(x) = x³ is at the origin, the same place it is shown on the graph. So, there is no translation involved in creating the graph.
We know the parent function gives f(1) = 1, but here, we have (x, y) = (1, -5). This suggests a vertical scale factor of -5. So, the transformed function is ...
y = -5x³
For a) simply substitute the speed of the car into the equation to get the braking distance.
For b) rearrange the equation to solve for x by substituting the braking distance in.
Rearranged, the equation looks like this: x = √(9d)
For c) use a calculator to find the precise value of x in question b.
0.4 x 25. this will give you 10
