How do I find the slope given the graph of a function?

It the graph linear? Can you identify two points on the graph?

If it is a linear function, we must identify 2 points. What if the graph is not linear? What if it is a trig function or cubic function or any other function that is a curve?

If the function is non-linear, then the slope will be a function instead of a constant, which is a topic for differential calculus. • harpazo

Yes, the derivative represents the instantaneous slope or rate of change.

I like the idea of the derivative.

Note:

I was thinking about putting aside my college algebra textbook and jumping right into calculus 1. Mark, my goal is to "master" calculus 1-3, if that's even possible. All doctors get the same training in college but eventually they branch off into individual specialties in medical school.

Calculus covers algebra, geometry, trigonometry and precalculus topics to a certain extent. DO YOU THINK I SHOULD JUST SOLVE CALCULUS PROBLEMS? There's a person online known as the calculus guy. He knows most math courses taught before calculus 1 but his specialty is single variable and multivariable calculus. This is where I want to be. What do you say? I want people to say HARPAZO IS THE MAN TO CONTACT FOR ANYONE TAKING CALCULUS 1-3. I want to be the next James Stewart.
