1. The problem statement, all variables and given/known data

The question is: How would you explain the chain rule to a classmate?

My teacher wants: 1.a graph, 2. in words, 3. using math
2. Relevant equations

3. The attempt at a solution

I said: for the function y=f[g(x)], the chain rule is d/dx[g(x)].

Whats the graph like?

What do you mean by d/dx[g(x)]?

DERIvative of g(x)...

You should have written it as: $$y'(x) = f'(g(x))g'(x)$$. What you have written is not the chain rule.
