Answer 1

wt hapnd?

Answer 2

I need help from the master. lol

Answer 3

html1618 is pretty good as well:-)

Answer 4

pfft. lol

Answer 5

A graph of a function f is shown. find f(2).. How do I do it?

Answer 6

Well, I can't see it but f(2) means the value at x = 2.

Answer 7

draw a vertical line upward frm x = 2, and from the point it meets the graph, draw a horizontal line to the y-axis. The value where it touches the y-axis is the value of f(2)

Answer 8

yes but I dont have a clue what I am looking for on this graph

Answer 9

first look for x=2 on the x-axis

Answer 10

found it?

Answer 11

yep

Answer 12

You wouldn't happen to have an equation to go with the graph, would you?

Answer 13

nope

Answer 14

I can tell you points on the graph

Answer 15

What does it look like?

Answer 16

Spanglish.. lol the points are (0,4) (-0.9,2.641) (-1.4,-1.824) (2,-4) (2.7,-3.587)

Answer 17

That (2,-4) looks good...

Answer 18

I'm sorry him1618, I don't see where.

Answer 19

fdget what i said...

Answer 20

its either A) -4, B)-1.34 C) 2.1 D)1

Answer 21

If you look at your list of points, you have a (2,-4) which means (x,y) is (2,-4) so...?

Answer 22

I have no idea.

Answer 23

OK, the graph is just the list of points, so (2,-4) is the point where x is equal to 2 and y is equal to -4, with me so far?

Answer 24

yes

Answer 25

Can you see that point on the graph?

Answer 26

when I draw a line up from 2 to intersect with one I draw from -4?

Answer 27

The x's go from left to right, minus to plus and
the y's go from top to bottom, minus to plus (The two lines crossing at (0,0) in the middle somewhere).

So you go along x until you get to 2 and then you go straight DOWN until you see -4 at the left (there should be a point (2,-4) there.

If you can't see it, I will do a picture...

Answer 28

I see that. But how do I go from there?

Answer 29

Well, remember, you said you wanted the value of f(2).

All that means is what is y when x is 2.

Well, you just found it.

Answer 30

Ok, I gave you a list of my answer options.. none of them make sense to me if I am understanding what you say

Answer 31

You have (2,-4) ie when x is 2, y is -4 so f(2) is -4 (your option A, I think)

Answer 32

O.. I misread I was thinking it said 4. Sorry, now I feel like a real idiot. Forgive me?

Answer 33

No problem, do you understand now how to "read" the graph?

Answer 34

I think I can, I think I can.. Only one more problem on this worksheet and 2 chapter sections tonight!!! We'll see if I got it or not. Thank you so much!

Answer 35

Just before you run off, what is f(2.7)?

Answer 36

7?

Answer 37

It's in your list of points as well as on the graph...

Answer 38

-4?

Answer 39

"Spanglish.. lol the points are (0,4) (-0.9,2.641) (-1.4,-1.824) (2,-4) (2.7,-3.587)"

-4 is close enough, you can see in the list it is actually -3.587

Good luck with the rest of your work:-)

Answer 40

Thanks again!!!!
