Question 417370: find the vertex, the line of symmetry, the maximum/minimum value of the quadric function and graph the function
f(x)3x^2-18+11
what is vertex
what is equation of the line of symmetry x=
what the maximum/minimum Answer by ewatrrr(24785) (Show Source):
Hi
Using the vertex form of a parabola, where(h,k) is the vertex
f(x) = 3x^2-18x+11 |completing the square to put into vertex form
f(x) = 3(x^2-6)+11
f(x) = 3[(x-3)^2 - 9]+11
f(x) = 3(x-3)^2 - 16 Vertex is Pt(3,-16), minimum at this Pt ( a>)
Line of symmetry is x = 3
