I'm not sure

You can integrate and function and then graph it, but you would have to be aware that the vertical position of each point is not fixed because of the constant which is added. The general shape of the graph would be correct.

I'm not sure that you can do it directly from the graph, without using calculus to integrate.

I'm sorry but this is not an equation because it does not have an equal sign.

Remember, calculators are not all the same.

5 and a half would often go is as
5 fractionbutton 1 fractionbutton 2

3 quarters would go is as
3 fractionbutton 4

Does that help?

Ok, thanks maths lover but it still doesn't make sense. I'll put my problems with the question in red.

in 1984 near ly 14% of all adults has no close friends.
On average the increase is 0.72% per year?
in 2006 it was 23.7 %

If it increased by 0.72% per year it would not be 23.7% in 2006. It would be 16.4%

write and equations nth term that gives the equation that has no close friends in 1983
