Question

Can someone help me with my math hw? <3

Answer 1

depends on the questions you have

Answer 2

ok one sec

Answer 3

@kkutie7

Answer 4

i haven't done that in a while! from what i remember you need you treat the number in the function as x. so if x=-4 what is y on the graph.

Answer 5

So, firstly you need to recognize that where there is a point with a hole, the function is not defined at that point, unless there is another point where there is not a hole.

Answer 6

From the first graph you have, this occurs at x=-3 and positive 3.
Notice the dot with the hole and the dot filled in. When looking for the values of x=-3 and x=3 you will take the y value of the filled in dot. Does that make sense?

Answer 7

yea im getting it a little @legomyego180

Answer 8

Do you know how to find the other values?

Answer 9

can u walk me through it and then i think ill be able to do the rest

Answer 18

wait i have a question so what about like f(2) for the first question

Answer 19

if no line is there what do u do

Answer 20

For f(2) y=-3

The line is still there its just below the x-axis now

Answer 21

ohhh

Answer 22

i have one more questin for f(5) would it be 5.5?

Answer 23

nope just 5

Answer 24

oh ok..can i do it and then u can check my work?

Answer 25

for sure

Answer 26

@legomyego180

Answer 27

Sorry I counted wrong on f(-4) it should be 4 not 5.
Other than that it looks good. You can calculate the value of h(4) and h(5) by finding the slop of the line.

h(4) would be 12 and h(5) would be 15 because your slope (rise / run) is 3/1.

Answer 28
