Extrema refers to the highest and lowest points of a function, which can be either maximum or minimum values.
X-intercepts: These are the points where a graph intersects the x-axis. They occur when y = 0.
Y-intercepts: These are the points where a graph intersects the y-axis. They occur when x = 0.
These are points on a graph where its derivative is either zero or undefined. They can be potential extrema.
