Question

Given this graph....

Answer 1

find domain and range

Answer 2

the domain is all the values that x can be,

Answer 3

find intercepts?

Answer 4

the smallest value x can be is -1

Answer 5

i think the domain is [-1,4]?

Answer 6

x is the first number in the order pair

Answer 7

i mean [-1,7]

Answer 8

thats better

Answer 9

and range is [-2,4]

Answer 10

that is right.

Answer 11

the intercepts are a bit more tricky, you might want to determine the gradient or slope

Answer 12

(in that region

Answer 13

ok, i'm going to do that now. would you say the graph is even, odd or neither? i think its neither?

Answer 14

yeah, is sure isn't even and it sure isn't odd

Answer 15

x int is 1/3?

Answer 16

and y int is -0.5

Answer 17

that is what i got for the x intercept ,
how did you get the y int?

Answer 18

and i can say that it is increasing on the interval [-1,3] and constant in the interval [3,7]? (or would i be using open brackets?)

Answer 19

i found the y int by making x =0

Answer 20

yeah y int is right too

Answer 21

your notation is correct, very good work

Answer 22

thanks for the help!:)
