Name ____________________________________________ MTH 1000 Test #2 1. [10pts] Find the coordinates of the vertex: f x 3x 2 12 x 5 f x 3x 2 1 2 2. Determine the end behavior of the following polynomials: [10pts] 3. [5pts] f ( x) 5 x 6 3x 1 Right: Left: f ( x) 2 x 3 22 x 48 Right: Left: Circle the appropriate equation which matches with the following graph: f ( x) x 1x 1 f ( x) x 1 x 1 2 f ( x) x 1x 1 2 f ( x) x 1 x 1 2 2 4. Divide the following polynomials and find a Quotient and a Remainder: [5pts] 5. 3x 4 5x 3 4 x 5 x 2 2 x 1 Identify the vertical asymptotes: [11pts] f ( x) 6. x3 x2 4 f ( x) x2 x 2 x 2 2x 3 Identify the horizontal or oblique/slanted asymptotes, if any exist: [11pts] f ( x) x 2 3x 5 2x3 4x 7 f ( x) x2 x 3 x2 7. Graph the following Rational Function: f ( x) x 2 4x 3 4 x2 [14pts] Vertical Asymptote(s): Horizontal/Oblique Asymptote(s): Determine the region(s) where the rational function is positive/negative. Combine all this information appropriately to generate the graph of the function. 8. Solve the following Inequalities: [14pts] 9 x 9. x 1 x 2 2 x 1 Find the roots of the following polynomial: f x 2 x 3 3x 2 8 x 3 [14pts] First, write the complete list of potential numbers that could be zeros according to the Rational Zeros Theorem: Now, identify a number from the list above which actually is a root, and then divide to find the remaining roots of the polynomial:
