MATH 111 - Exam 1 - Summer 2011 - Section 1 No books, notes, or calculators allowed. Do NOT write on this exam. There is no time limit. For problems 1-4 choose the equation that yields the given graph. 1. (a) ( x - 1) 2 + y 2 = 1 (b) ( x - 1) 2 + ( y - 2) 2 = 1 (c) ( x + 1) 2 + ( y + 2) 2 = 1 (d) ( x - 2) 2 + ( y + 1) 2 = 1 (e) ( x - 2) 2 + ( y - 1) 2 = 1 (f) ( x + 2) 2 + ( y - 1) 2 = 1 2. (a) 1 - x (b) 1 + x + 1 (c) 1 + x - 1 (d) 1 + - x + 1 (e) - 1 + - x + 1 (f) 1 - x + 1 3. (a) y = 2 | x | - 1 (b) y = 1 2 | x | - 1 (c) y = 1 2 | x | + 1 (d) y = | x | - 1 (e) y = | x | + 1 (f) y = - 2 | x | - 1

4. (a) y = ( - x + 1) 3 (b) y = ( x + 1) 3 (c) y = ( x - 1) 3 (d) y = ( - x - 1) 3 (e) y = x 3 (f) y = x 3 + 1 For problems 5-12, refer to the graph of y = f ( x ): Choose the graph for each of the following functions. An answer may be used more than once. 5. y = 2 f ( x ) 6. y = f ( x ) + 1 7. y = f ( - x ) 8. y = - f ( x ) 9. y = - f ( - x ) 10. y = f ( x + 1) 11. y = f ( 3 2 x ) 12. y = | f ( x ) |
