Question
Write each function in standard form . F(x)= - (x+3)2+8
Hint:
The standard quadratic form is ax2+bx+c=y, the vertex form of a quadratic equation is y=a(x−h)2+k.
The correct answer is: f(x) =-x2 - 6x - 1.
We have given the function in Vertex form , we have to convert it into standard form.
F(x)= - (x+3)2+8
On further solving this function we will get
F(x) = - ( x2 + 6x + 9 ) + 8
= - x2 - 6x - 9 + 8
= - x2 - 6x - 1
Therefore, the standard form of given function is f(x) =-x2 - 6x - 1 .
