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,  ...

Praxis- Mathematics Questions and Answers 100% Pass In the proceeding figure, P and T are points on like k, and points Q, R and S are points on line l. Lines k and l are parallel. What is the measure of the angle TRS? Since angles PTR and TRS are alternate interior angles, they are congruent and they have the same angle measure. The equation: 5x + 10 + 110 = 8x+102 x=6. The measure of angle TRS is 8 x 6 + 102 = 150 degrees. The following table shows the distribution of 50 cookies sold in a sto...
