For each function, choose whether it’s graph opens upward or downward. Choose the equation with the narrowest graph. Choose the equation with the way this graph.

a. A = positive
B = positive
C = negative
D = negative
b. The coefficient closest to 0 is A because as x increases, y increases at lowest rate (you can say that the wider graph the lower coefficient is)
Answer: A
c. The coefficient with the least value is A
Answer: A
