Question

3. For questions 3–4, order the group of quadratic functions from widest to narrowest graph.

y = 3x2, y = x2, y = 2x2 (1 point)

y = 2x2, y = x2, y = 3x2
y = 3x2, y = 2x2, y = x2
y = x2, y = 2x2, y = 3x2
y = x2, y = 3x2, y = 2x2

4. y = –5x2, y = –x2, y = –4x2 (1 point)

y = –x2, y = –5x2, y = –4x2
y = –x2, y = –4x2, y = –5x2
y = –5x2, y = –4x2, y = –x2
y = –4x2, y = –x2, y = –5x2
