question 63

Multiple Choice

Find the coordinates of the vertex and the intercepts of the quadratic function. When necessary, approximate the
x-intercepts to the nearest tenth.
- $$s ( x ) = - x ^ { 2 } - 10 x + 39$$

• A) \(\mathrm { V } ( - 10 , \quad ) ; \mathrm { I } ( 0 , \quad ) ; ( - 10,0 ) ; ( 10,0 )\)
• B) \(\mathrm { V } ( - 5,64 ) ; \mathrm { I } ( 0 , \quad ) ; ( , 0 ) ; ( - 13,0 )\)
• C) \(\mathrm { V } ( 5,64 )\); \(\mathrm { I } ( 0,39 )\); no \(x\)-intercepts
• D) \(\mathrm { V } ( 10,39 )\); \(\mathrm { I } ( 0 , - 39 ) ; ( 13,0 )\); \(( - 3,0 )\)
