2. the range of the following relation: r: {(3, -2), (1, 2), (-1, -4), (-1, 2)} is (1 point) a) {-1, 1, 3} b) {-1, -1, 1, 3} c) {-4, -2, 2, 2} d) {-4, -2, 2}

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8
