Adding Fractions Simplifying Products and Quotients Involving Square Roots Simplifying Square Roots That Contain Variables Analyze the critical points of a function and determine its critical points (maxima/minima, inflection points, saddle points) symmetry, poles, limits, periodicity, roots and y-intercept. Likewise, a relative maximum only says that around (a,b)(a,b) the function will always be smaller than f(a,b)f(a,b). When working with a function of one variable, the definition of a local extremum involves finding an interval around the critical point such that the function value is either greater than or less than all the other function values in that interval.
