You can find maximum/minimum points of some functions without differentiation. If it's a quadratic function, you can complete the square, and then find it from there - the minimum point of will be when , as then , whereas all other values of would give .
They often have exam questions where one part will be completing the square, and then the next will be finding a maximum/minumum point of the function.
