Which of the following best describes how the y values are changing over each interval? they are increasing by 20 each time. they are increasing by 40 each time. they are being multiplied by 2 each time. they are being multiplied by 4 each time.

C: They are being multiplied by 2 each time.

Step-by-step explanation:

x         y                Reason:            

1        20

2       40                 2 x 20 = 40

3       80                 2 x 40 = 80

4      160                 2 x 80 = 160

5      320                2 x 160 = 320

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

6 meters
