−seven eighths

Answer 1

rate of change formula

Answer 2

what is the value of the function when x = 4?

Answer 3

huh o.o

Answer 4

look at the graph

what's the value of the function when x = 4?

Answer 5

Oh wait -5?

Answer 6

good, now what about the value when x = -4?

Answer 7

do i go left from -4

Answer 8

look at where the giant blue dot is and find the matching y- value

Answer 9

in this case you would go to the right

Answer 10

the idea is to go towards the y-axis

Answer 11

>.< This is confusing...

Answer 12

put your eye on the dot where x = -4

go straight to the right until you touch the y-axis

what number do you get?

Answer 13

0?

Answer 14

good

Answer 15

so using our formula we have

(-5 - 0) / (4 - (-4)) = ?

Answer 16

-5/8?

Answer 17

good so -5/8 = your answer
