Four Ways to Represent a Function 1. The functions () =  + √2 −  and () =  + √2 −  give exactly the same output values for every input value, so  and  are equal. 2. () = 2 −   − 1 = ( − 1)  − 1 =  for  − 1 6= 0, so  and  [where () = ] are not equal because (1) is undefined and (1) = 1. 3. (a) The point (−2 2) lies on the graph of , so (−2) = 2. Similarly,  (0) = −2,  ...

Question 1 1.1 Rote learning can never be used to replace high-level thinking. It is, however, crucial for achieving high-level thinking. 1.1.1 When is rote learning necessary in mathematics? (2) Rote learning is necessary in mathematics when learning basic facts or formulas that need to be memorized in order to solve more complex problems. For example, in algebra, students need to memorize the quadratic formula in order to solve quadratic equations. In geometry, students need to memorize...
