Fermat's Theorem says that the only points at which a function can have a local maximum or minimum are points at which the derivative is zero or the derivative is undefined. As an illustration of the first scenario, consider the plots of {{MATH_143}} and {{MATH_144}}. {{CMD_145}} {{ENV_146}} {{COMMENT_147}} {{COMMENT_148}} {{CMD_149}} {{CMD_150}} Make a correct choice that completes the sentence below. {{CMD_151}} At the point {{MATH_152}}, the function {{MATH_153}} has
