20. Find a quadratic function to model the values in the table.

A. y = -2x^2 - 3x + 3

B. y = 3x^2 + 3x - 3

C. y = -3x^2 - 3x - 3

D. y = 2x^2 + 3x + 2

1:A

2:B

3:A

4:D or A po ata

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
