Answer:
Maximum or minimum
Step-by-step explanation:
An extreme value of a function are the highest and lowest points on the function. This is where the y-value is at its highest or lowest values. If a function is continuous and approaches infinity or negative infinity on either end, then its extreme values are local maximums or minimums. These are max and min over a specific part of the function. They are called local since the function continues in one or both directions forever.
