Square root function

6) Predict below what would happen if multiple changes were made at once. Then check your answer.

a = 2, b = 2, c = 2

Prediction:

a = -1, b = -5, and c = -5

Prediction:

7) Now that you have seen the changes in the graph as you controlled the variables can you explain why each variable has the effect it has?

Effect and explanation of a:

Effect and explanation of b:

Effect and explanation of c:

8) Below is the equation for speed (y) that a car was traveling given the length of the skid mark (x) that the car created once the brakes were applied.

9) Change the two equation below to reflect how this equation might change if the car had high end brakes and tires or if the car was braking in the rain.

High end brakes or tires:

Driving in the rain:

10) Does it make sense that this equation would ever be negative for y or for x?

Explain:

How would
