So I have to do a chart graph thing but for an equation, I don't know how to do the tilde mark with a Chromebook and nothing is really helping me of how to do it
1.
2.
3.
4.
5.
1. y = x^2 - 4x + 1
2. y = .782x^2 - 20.213x + 179
3. y = 0.032x^2 - 0.601x - 0.255
4. y = -3.5(3)^2 - 0.5 (3) + 65 = 32 in
5. y = 1.65 (8)^2 + 18.25(8) + 155 = 406.6 = $407, 000
