SOLUTION: Write the function in the form f(x)=a(x-h)^2+k by completing the square . F(x)=x^2+16x-9

Question 969084: Write the function in the form f(x)=a(x-h)^2+k by completing the square . F(x)=x^2+16x-9
Answer by MathLover1(20849) (Show Source): You can put this solution on YOUR website!
the function in the form will be:
....recall the rule:
when you compare it to your function, you can see that and
since we need to complete the square, we can calculate it from
=>=>=>=>
so, we add and subtract

where and ;so, vertex is at (,)
