Discuss 144 to 145.
Whiparound Each group shares something.
144:
145:
The graph is flat Sshaped and increasing everywhere; x and yintercepts are both at the origin; any value can be input, any value can be the output; there is no maximum or minimum; the origin is a special point because that is where the “S” turns direction; there are no lines of symmetry.
The graph is Vshaped; it decreases first, and then after the origin it increases; the x and yintercepts are both at the origin; any input is possible, but the outputs are all positive or zero; there is a special point at the origin at the point of the “V” shape; there is a line of symmetry at the yaxis. All values of x are allowable. Values for y are limited to those greater than or equal to zero.
146: The graph is a “V” opening up. As x increases, y decreases until x = , then y increases. There is a minimum point (the vertex) at (0.5, 0). This is also the x‒intercept. The y‒intercept is (0, 1). There is a vertical line of symmetry through (0.5, 0).
