part a
describe a relationship that can be modeled by the function shown in the table, and explain how the function models the relationship.
x f(x)
1 4
4 8
9 12
16 16
25 20
part b
then, identify and interpret the key features of the function in the context of the situation you described in part a.

Equation: y=4√x

Step-by-step explanation:

This is a square-root function, specifically y = 4√x. As the input increases, the output also increases. It can also be written in exponent form, y = 4 * x^(1/2). The curve gets closer and closer to horizontal as the input increases, although it never does. The inverse of this function is y = (1/16)x², a quadratic, you can imagine y = 4√x being a reflection of y = (1/16)x² across the line y=x.

A. One relationship the function possibly models is the relationship between velocity and braking time. Imagine this situation: A function for the distance (in meters) at which a car need to stop is given by D = 4 √v where v (in meters per second) is the speed of car before braking.

B. At the beginning, when v = 0, your car is at rest, so D also = 0. At v = 9m/s, you need 12 meters to stop completely.  At v = 100, you need 40 meters to stop completely.

I'm not sure if I answered your question. Hope I helped!    

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.
