Question

In each case, from the coordinates of the given point, write the rule of the quadratic function

a: (6, 216)
b: (-4, 128)
c: (7, -490)
d: (0.5, 8)
e: (-4.5, -40.5)
f: (8, 16)
g: 8, 1/2)
h: 9, 275.4)
I: (10, -48)

Answer 1

a: y = 6x²

b: y = 8x² + 64x + 128

c: y = -23x² + 322x - 1056

d: y = 64x² - 64x + 8

e: y = -9x² - 81

f: y = -4x² + 64

g: y = -2x² + 8x

h: y = 1.4x² - 25.2x + 118.4

i: y = -18x² + 180x - 680
