(a) What is the vertex of the function? Show your work.
(b) What is the equation of the axis of symmetry? Explain how you know.
(c) What is the y-intercept? Explain how you know.
To find the vertex rewrite in vertex form and use this form to find the vertex (h,k). Â To find the y-intercept, substitute in 0 for x and solve for y.
