Unformatted text preview: sakerwalla (hs9229) – HW1 – milburn – (54685) 1 This print-out should have 24 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Which, if any, of the following statements are true when a, b are real numbers? A. For all positive a and b , √ a + b = √ a + √ b . B. For all a and b , radicalBig ( a + b ) 2 = a + b . C. For all positive a and b , a − b √ a + √ b = √ a − √ b . 1. A only 2. none of them 3. A and B only 4. B and C only 5. B only 6. C only 7. A and C only 8. all of them 002 10.0 points Simplify the expression f ( x ) = 3 + 9 x − 2 1 − 3 parenleftBig x x 2 − 4 parenrightBig as much as possible. 1. f ( x ) = 3( x + 2) 2 x − 4 2. f ( x ) = 3( x − 2) x − 4 3. f ( x ) = x − 2 x + 4 4. f ( x ) = x − 2 2 x + 4 5. f ( x ) = x + 2 x + 4 6. f ( x ) = 3( x + 2) x − 4 003 10.0 points Let f be the quadratic function defined by f ( x ) = 2 x 2 + 4 x + 20 . Use completing the square to find h so that f ( x ) = 2( x + h ) 2 + k for some value of k . 1. h = − 2 2. h = 1 3. h = 2 4. h = 4 5. h = − 1 004 10.0 points By removing absolute values, express f ( x ) = x 2 − 9 | x + 3 | as a piecewise-defined function. 1. f ( x ) = braceleftbigg x + 3 , x > − 3 , − ( x + 3) , x < − 3 . sakerwalla (hs9229) – HW1 – milburn – (54685) 2 2. f ( x ) = braceleftbigg 3 − x , x > − 3 , x − 3 , x < − 3 . 3. f ( x ) = braceleftbigg x − 3 , x > − 3 , 3 − x , x < − 3 . 4. f ( x ) = braceleftbigg x + 3 , x > 3 , − ( x + 3) , x < 3 . 5. f ( x ) = braceleftbigg x − 3 , x > 3 , 3 − x , x < 3 ....
