Answer 3

the function is increasing if you read it from left to right and the graph is going up (ie the slope is positive)

the function is decreasing if you read it from left to right and the graph is going down (ie the slope is negative)

Answer 4

so its Increasing x < -1; Decreasing x > -1

Answer 5

you sure?

Answer 6

the piece that's below x = -1

that piece is increasing?

Answer 7

ok, so x is less than 1 and when its decreasing, x is greater than 1

Answer 8

now you're just guessing, please don't just guess

Answer 9

im confused. you said that theres a piece below negative 1, but i ony see it at -1

Answer 10

look at the left piece, is that increasing? or decreasing?

Answer 11

decreasing

Answer 12

so it's decreasing when x < -1

Answer 13

ok

Answer 14

do you see how it's decreasing when x is less than -1?

Answer 15

yes, i can see what your saying now

Answer 16

ok great
