Question

What is the vertex for the function? (You will want to find the axis of symmetry first.) Write as an ordered pair, leaving no spaces, such as (1,-4).
y = -3x2 + 6x

Answer 1

in your equation, do you know the value of -b/2a gives you?

Answer 2

i dont understand what your asking me?

Answer 3

your equation is that of a parabola: f(x) = ax^2 + bx + c,
where a, b, c are coefficients.

do you know what -b/2a gives you?

Answer 4

no?

Answer 5

i dont understand this question at all..

Answer 6

really? this is a quadratic function... it's graph is called a parabola.

Answer 7

-b/2a will give you the x coordinate of your line of symmetry. this is also the x coordinate of your vertex (what you asked for).
