(f+g) (2)
I think this means f(2) + g(2)
We're told that (2,1) is on the curve so f(2) = 1
We're told that (2,2) is on the line so g(2) = 2
So (f+g)(2) = 1 + 2 = 3
And so on.

Perfect. I will do the rest and, if tune allows, post the rest here.

I assume you wanted the image to display...which it can't, for 2 reasons:
1. Your img tags have spaces, which render them invalid.
2. The link is to the webpage containing the image and not to the image itself.
The image link (see below) is very different from your webpage link, as you can see:

Just copy the above text and paste it into a post to display the image.
Alternatively, you could've put your webpage link in url tags, like so:
[url=https://i.imgur.com/a/gpB0TL4]Graph of Two functions[/url]
Here it is: Graph of Two functions.
1. The link is clickable, making it easier to view the webpage.
2. I gave the link a title (ie, your thread title), and the link shows how that's done.

I don't know what you mean by copy and paste the link.

I don't know what you mean by copy and paste the link.
I've changed my wording in that post to try and make it clearer. It's now:

Following on from my previous post...
This is the link text from my previous post:
[img]https://i.imgur.com/7NtStGD.jpeg[/img]
Clicking the 'Preview' button shows that the image will be HUGE, so I'll place the size modifier letter "l" (for "large") before the image extension (".jpeg") to reduce the image size from huge to large (I described that Imgur feature here).
With the size modifier "l" added, my link (including img tags) becomes:
[img]https://i.imgur.com/7NtStGDl.jpeg[/img]
Now I'll copy that, and paste it into this post.
Here goes...
And there's the image.

Ok. I will to upload another graph later or tomorrow.

I think this means f(2) + g(2)
We're told that (2,1) is on the curve so f(2) = 1
We're told that (2,2) is on the line so g(2) = 2
So (f+g)(2) = 1 + 2 = 3
And so on.

Hi Bob.
Here are the rest.
b. (f + g)(4) = f(4) + g(4) = 1 + (-3) = -2
c. (f - g)(6) = f(6) - g(6) = 6 - 1 = 5
d. (g - f)(6) = g(6) - f(6) = 6 - 0 = 6
e. (f • g)(2) = f(2) • g(2) = 2 • 1 = 2
f. (f/g)(4) = f(4)/g(4) = 1/-3 = -1/3.
You say?

b e and f look ok.
c and d ought to be same except one is minus the other.
Check out your values for g(6) and f(6) carefully.

c. 6 - 1 or 5
d. 1 - 6 or -5
Got it!

The points for these two are (6,1) and (6,0). The dependent numbers are 1 and 0, ....... no 6 please.

Yes, you are right.
Then, 1 - 0 = 1 and 0 - 1 = -1.
