Answer 5

Hello. :3
Okay, so I haven't done this in a while, but I'll still help because I think I still remember. If anyone else notices I did something wrong, just let us know. Thanks!

Okay, so the graph itself is graph f. Do you understand that?

Answer 6

Yes

Answer 7

Okay, so for the first part, you have to find f(1). Basically, f(x) = the y-value and x obviously equals the x-value. So this means that You are finding the y-value for when x = 1.

Answer 8

Is 2 a reasonable answer?

Answer 9

2 is a reasonable answer. It's hard to tell honestly because the graph only has 0 and 5, but it seems reasonable. I'd say 2.

Answer 10

Now, for the second question;

So do you know where f(40) would be at?

Answer 11

I was thinking positive because 40 x would be positive. No?

Answer 12

Correct!

Answer 13

Wait omg wait. I think we might be incorrect actually.

Answer 14

Yeah, we are incorrect. Okay, so remember 40 is the x-value. But remember that the y-values of the graph decrease as you go more to the right of the graph. So as the x-values increase, the y-values decrease. So it would actually be negative. The graph basically explains it once you realize it.

Answer 15

That makes sense

Answer 16

Okay, perfect!

Answer 17

And I have to go. But the last question seems different, but it is exactly the same as the first question. It's just re-worded basically. That should help.

Answer 18

What about for the last one?

Answer 19

I just explained it ^^

Answer 20

Okay

Answer 21

I got 0 . Can anyone confirm????

Answer 22

This question is unfair because they failed the label the axis properly. Anyways, draw a horizontal line through y = 2 and see where it crosses the graph. If f(0) = 2, then x = 0 is one of the x values. There will be two other x values

Answer 23

-2 and 1??

Answer 24

oh wait, nvm, you said f(1) = 2. I misread

Answer 25

If f(1) = 2 is correct, then x = 1 would be one of the x values

Answer 26

no f(x)=2

Answer 27

I see they have this covered, ask me if you need any help!

Answer 28

no f(x)=2

Answer 29

It's impossible to tell really without accurate labels/numbers on the axis. But if f(1) = 2 is true and this point is at the peak, then x = 1 is one of the x values. Draw a horizontal line from this peak point until you hit the graph again. Where is this other point?

This point would be (x,2) where x is some negative number
