y = 2x² + 4x - 5

y = 2x² - 4x + 5

y = 2x² + 4x + 5

y = 2x² - 4x - 5

y = -2.7x + 7.4

y = 0.95x² - 2.08x - 0.75

y = -.05x - 3.26

y = 0.95x² + 2.08x + 0.75

y= -18x² + 2.11x + 4.21

y= -.06x² +1.06x + 7.9

y= -6x² +1.06x + 79

y= -.12x² + 2.11x + 4.22

Y = 8.16(2.7)^X

Y = 81.6(2.7)^X

Y = 8.16(.27)^X

Y = 8.16(27)^X
