How to plot a function that relies on another function?

Hello, so I want to plot X on the Y-axis with Y on the X-axis with Y ranging from [-10 10]. However values of X depend on A which depends on Y so I cant figure out how I can plot Y with values ranging from [-10 10] and have X on the Y-axis. I realize I can initially make Y an array but i want infinite data points in the interval. Sorry if the wording is confusing.

sorry this is my first post I dont know why it printed out like a line of code

I don't think it is anything that you did: some recent changes to this forum seem to incorrectly format the first paragraph as code, I have seen quite a few questions like this in the last week or so.

I just fixed your question by selecting the text and clicking the TEXT button:

Since ‘A’ is a function, it must be evaluated in order to use its results.

Try this:

A = @(y) y*2;
X = @(y) A(y)+10;

figure
fplot(X, [-10 10])

Also, note the slight changes in the code.

Thankyou!!! and what does figure do?

As always, my pleasure!

the figure call creates a figure object so that if there are any otther plot objects existing, it will not over-write them. I always create a figure object when I want to plot something, for that reason.
