- Q7Which set of ordered pairs does NOT represent y as a function of x?{(4, -4), (3, -3), (-2, 2), (10, -10)}{(4, 7), (3, 6), (-5, 3), (4, 3)}{(0, 3), (5, 3), (6, 3), (-4, 3)}{(-2, 1), (-4, -1), (-3, 0), (5, -5)}30s8.5.G: Proportionality
- Q8Which representation shows y as a function of x?30s8.5.G: Proportionality
- Q9Which statement describes the mapping?The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value.The mapping does not represent y as a function of c, because 2 of the x-values correspond to the same y-value.The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.The mapping does not represent y as a function of x, because there are more x-values that different corresponding y-values.30s8.5.G: Proportionality
- Q10Which representation does NOT show y as a function of x?{(3, 2), (5, 6), (-2, 2), (-12, 5)}30s8.5.G: Proportionality
