3 0

Answer:

Step-by-step explanation:

The shape of the graph is called a PARABOLA.

The domain of the function is the set of all real numbers, and the range of the function is the set of all real numbers greater than or equal to (-4).

[Parabola is opening upwards and the lowest point is it's vertex (2, -4). Therefore, range of the function will be y ≥ -4]

When x = -1,

Value of the function 'f' will be,

f(x) = 5

[Graph passes through (-1, 5)]

RSB [31]

Answer:

The answer to your question is speed = 9 m/s

Step-by-step explanation:

Data

Winner                                 Last runner

time = 45 s                           time = 48 s

speed = 9.6 m/s

Process

1) Calculate the distance they ran using the data of the winner

      speed = distance / time

-Solve for distance

      distance = speed x time

-Substitution

      distance = (9.6)(45)

-Result

      distance = 432 m

2.- Calculate the speed of the last runner

-Substitution

      speed = 432/48

-Result

     speed = 9 m/s
