What is the general form of the chain rule used for derivatives?
If we have f(g(x)), where g(x) is a function inside the function f(x), the derivative of f(g(x)), denoted: d/dx[f(g(x))] is equal to f'(g(x))*g'(x).
Solve the equation: 2x-5=15
2x-5=15 2x-5+5=15+5 2x=20 2x/2=20/2 x=10
What does the slope of the indifference curve tell us?
The slope of the indifference curve is the marginal rate of substitution of good x for good y.
