QUADRATIC FUNCTION REVIEW COMMON CORE ALGEBRA II HOMEWORK FLUENCY 1. Without the use of your calculator, evaluate each of the following quadratic functions for the specified input values. (a) g(x) = x -9 ( b) f ( x ) = - 2x + 8x (c) h (x) =x-2x+6 8 ( 5) = f ( 3 ) = h (0 ) = 8 (- 3) = f ( - 1 ) = h ( - 2 ) = 2. Which of the following represents the y-intercept of the graph of the quadratic function y = 2x2 - 7x+9? (Recall, that the y-intercept of a graph always occurs when x = 0.) (b) (1) 7 (3) -7 (2) 2 (4) 9 3. For a particular quadratic function, the leading coefficient is negative and the function has a turning point whose coordinates are (-3, 14). Which of the following must be the range of this quadratic?
