Find and label the vertex and the line of symmetry. Graph the function f(x) = 5x^2
The vertex is _____
(write an ordered pair)
10 points to the first correct answer
A function of the form f(x) = a(x-k)² + h has a vertex at the point (k, h) and the line of symmetry is the line x = k.
The function f(x) = 5x² can be written as f(x) = 5(x-0)² + 0, so h = 0, k = 0 and the vertex is at (0,0) and the line of symmetry is x = 0.
