Question 971938: If the graph of a function of the form y = ax^2 + c has a vertex located above the origin and opens downward, which of the following must be true about the values of a and c?
a. a < 0 and c > 0
b. a > 0 and c > 0
c. a < 0 and c < 0
c. a > 0 and c < 0 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! If the graph of a function of the form y = ax^2 + c has a vertex located above the origin and opens downward, which of the following must be true about the values of a and c?
-----
a<0 since the graph opens downward.
----
c >0 so the y-intercept is above the origin.
