Unformatted text preview: + + = ax2 bx c 0 EXAMPLE: Graph =+ fx x2 6x 5 1. The graph opens up since a>0 2. The vertex is ( ) ( )= = =( ) + = + = , 6 2 1 62 3 and f3 3 2 63 5 9 18 5 4 The vertex ( , ) is 3 4 3. =+ = ( , ) f0 02 60 5 5 y intercept is 0 5 4.+ = x2 6x 5 0 5. = x 5x 1 0 6. =  = x 5 0 or x 1 0 7. = = , , x 5 or x 1 the x intercepts are 5 0and 1 0 8. I could not figure out how to make a graph to show it visually 9. 10. The quadratic equation is = + x b b2 4ac2a 11. If we use our above equation; =+ , = , = , = fx x2 6x 5 a 1 b 6 c 5 12. =( )( ) ( ) ( ) x 6 6 2 41 5 2 1 13. = x 6 36202 14. = x 6 162 15. = = x 6 42 3 2 16. = = x 5 or x 1 17....
