Find the Vertex, the Y-Intercept, and the X-Intercepts (If Any $$r ( x ) = x ^ { 2 } - 6 x + 9$$

question 79

Multiple Choice

Find the vertex, the y-intercept, and the x-intercepts (if any exist) , and graph the function.
- $$r ( x ) = x ^ { 2 } - 6 x + 9$$

• A) Vertex \(( 0 , - 9 )\) \(x\)-int \(= ( 3,0 )\), \(( - 3,0 ) ; y - i n t = ( 0 , - 9 )\)
• B) Vertex \(( 0,9 )\) no \(x\)-intercepts; \(\mathrm { y }\)-int \(= ( 0,9 )\)
• C) Vertex \(( 3,0 )\) \(x\)-int \(= ( 3,0 )\); \(y\)-int \(= ( 0,9 )\)
• D) Vertex \(( - 3,0 )\) \(x\)-int \(= ( - 3,0 )\); \(\mathrm { y }\)-int \(= ( 0,9 )\)
