Turning points- where the graph of a function changes from increasing to decreasing or vice versa

Local maximum point – highest point or “peak” in an interval
function values at these points are called local maxima

Local minimum point – lowest point or “valley” in an interval
function values at these points are called local minima

Extrema – plural of extremum, includes all local maxima and local minima
