Step-by-step explanation:

First image with two graphs:

1. This is a function (Yes)

The domain is $x\in [-5,5)$

The range is $y\in (-2,2]$

2 (that graph from the third image). This is not a function (No)

The domain of this relation is $x\in (-3,5]$

The range is $y\in (-2,2)$

Second image (parabola):

This is a function (Yes)

The domain is $x\in (-\infty, \infty)$

The range is $y\in (-\infty,0]$

Fourth image (cubic parabola):

This is a function (Yes)

The domain is $x\in (-4,3)$

The range is $y\in (-2,4)$

A tortoise and a hare are competing in a race around a 1600-meter track. The arrogant hare decides to let the tortoise have a 78

Sindrei [870]

I am presuming that the question is who won or by how much did the winner win.

distance equals rate times time, or d = r*t
For the Hare d = 1600 and r = 10
1600 = 10 t
Divide both sides by 10
t = 160
The hare finished in 160 seconds

For the tortoise d = 1600 - 780 = 820 (due to the head start) and r = 5.3
820= 5.3 t
Divide both sides by 5.3
t = 154.72 (rounded to the hundredths place)

The tortoise won by 5. 28 seconds (160-154.72)
