MM2A3. Students will analyze quadratic functions in the forms f(x) = ax2+ bx + c
and f(x) = a(x – h)2+ k.
c. Investigate and explain characteristics of quadratic functions, including
domain, range, vertex, axis of symmetry, zeros, intercepts, extrema, intervals
of increase and decrease, and rates of change.
How to find the vertex and axis of symmetry
step 1 the vertex of a vertex form equation in (h,k)
step 2 the axis of symmetry is h
(A hint is to take the opposite sign of h)
ex. Find the vertex and aos of 2(x-1)^2+3
answer is vertex (1,3) and the aos is 1
and f(x) = a(x – h)2+ k.
