question
you must find the axis of symmetry of the function f(x). choose the form of the quadratic function f(x) that you would like to see in order to answer the question most efficiently.
answer attempt 1 out of 2
general form
factored form
vertex form

Explanation:

The vertex form of a quadratic function is $f(x)=a(x-h)^2+k$, where $(h,k)$ is the vertex. The axis of symmetry is the vertical line $x=h$, which is directly visible from this form without extra calculations. General form ($ax^2+bx+c$) requires using $x=-\frac{b}{2a}$, and factored form requires averaging roots, making vertex form the most efficient.

Answer:

Vertex form
