- Determine whether each coefficient is positive or negative
- Choose the coefficient closest to 0
- Choose the coefficient with the greatest value
1) First and last coefficients are negative because graph is on negative side of y axis. Second and third are positive because graph is on positive side of y axis.
2) Coeff. closest to 0 is C because as x increases c*x^2 = y increases at lowest rate (you can say that the wider graph the lower coefficient is)
3) Oposite from 2. Coeff with greatest value is A
Graph A & C are negative
Graph B & D are positive
The coefficient closest to 0 is B
The coefficient with the least value is A
Hope this helped :3
