5. If graphed, which of the following parabolas would lie entirely below the x-axis? (1) y=x² +5x+10 (3) y=-2x²+6x-5 (2) y=-2x²-5x+3 (4) y=x² +6x+9 6. Which parabola below, when graphed, would cross the x-axis at two unequal irrational locations? (1) y=2x² +11x+12 (3) y=9x² - 6x +1 (2) y = xỉ +2x−4 (4) y = 2x2+4x+9 REASONING 7. Determine all values of a that will cause the parabola y=ax² +10x+1 to cross the x-axis at two distinct locations.
