Graphing and sketching is a really big part of mathematics.
Firstly, we have a nice overview of all the types of graphs that you can expect to see, and there is a lot of them! Don’t worry though, you can remember them.
overview
trig functions
Trig functions are really beautiful. They appear everywhere in nature and are the very embodiment of energy and movement.
Anyway, they have amplitudes and periods.
power functions
Power functions can be a pain because there can be so many exponents, and you have them in fractions and you have then negative and all that.
Oh well, there’s a lot of them.
polynomial
how to graph polynomial functions
Polynomials are common in mathematics because they have a lot of factors, and the x and y intercepts of polynomials can be useful in application problems.
