Question

do now 2/11
which one of these does not belong? explain why

Explanation:

All graphs are parabolas (quadratic functions). Graphs a, c open upward (positive leading coefficient), graph d opens downward (negative leading coefficient). Graph b is the only one that is not a smooth, continuous parabola with a single vertex; it has flat, horizontal segments, making it a piecewise function rather than a standard quadratic parabola.

Answer:

b. The second graph (labeled b) does not belong, as it is a piecewise function with flat horizontal sections, unlike the others which are smooth, continuous quadratic parabolas.
