Name: ______________________ Class: ______________________ Date: _____________ Exam 3: Function Graphs & Systems Released Version 1. The function f(x) = |x| is changed to g(x) = (¼) |x-5| - 2 Which of the below correctly identifies the transformations? A.  Horizontal Shift UP by 2 Units  Vertical Shift Right by 5 Units  Stretch with a scale factor of 5  It reflects over the x-axis. B.  Horizontal Shift Right by 5 Units  Vertical Shift Down by 2 Units  Compression with a scale factor of (1/4)  There is no reflection over the x-axis. C.  Horizontal Shift Left by 5 Units  Vertical Shift Down by 2 Units  Compression with a scale factor of 5  It reflects over the x-axis. D.  Horizontal Shift Left by 5 Units

 Vertical Shift Down by 2 Units  Compression with a scale factor of (1/4)  It reflects over the x-axis. 2. Given function f(x) = - (x-3)² + 1, which statements represent key attributes of this function? Select TWO correct answers. A. The vertex is (-3,1). B. The maximum is y = 1. C. The range is y≥1. D. There is an x-intercept at (2,0) E. There is an x-intercept at (0,-8). 3. Given the function f(x) = √( x-4)+2 , identify the correct domain and range. A. Domain: (-∞,∞) Range: (-∞,∞) B. Domain: [-4,∞)

Range: [2,∞) C. Domain: [4,∞) Range: [2,∞) D. Domain: (4,∞) Range: (2,∞) 4.

Identify the aymptote for the graph pictured above.

A. y = -1 B. x = -1 C. y = 0 D. x = 3 5. Nick has 40 coins consisting of in nickels, dimes, and quarters. He has 3 times as many nickels as dimes. If the coins are worth a total of $4.00, which system of equations is used to determine how many of each coin Nick has? A. n + d + q = 40 n = 3d .05n + .10d + .25q = 4.00 B.

n + d + q = 40 d = 3n .05n + .10d + .25q = 4.00 C. n + d + q = 40 n = 3d 5n + 10d + 25q = 4.00 D. n + d + q = 40 d = 3n 5n + 10d + 25q = 4.00 6. Which equation is used to find one of the solutions to the equation -142x-6=-11 A. -14(2x-6)=11 B. 2x-6=114
