leading coefficient is positive
as with all polynomials, the domain is all reals
Since there is a vertex, the range is all reals above/below the vertex, depending on the leading coefficient.
Fire away!
Determine the characteristics of the quadratic function:
y = 4(x + 5)(x – 2)
Organize these in a chart form, with rows for "Domain", "Range", "Vertex" and "Opens: (Up/Down)"
