no one said anything about which way the graph opens.
Actually, without looking at the graph, there is no way to answer the question.
But, if there are 2 roots, then for sure C is correct, because
if it opens up, then the vertex is below the x-axis
if it opens down, then the vertex is above the x-axis.
the equation is f(x)=a(a-p)^2+q. Which statment is true?
A. a is less than zero because the graph opens upwards a q is zero because there are 2 x-intercepts
B. a is greater than zero because the graph opens upwards a q is zero because there are 2 x intercepts
C. the values a and q have opposite signs because there is 2 xintercepts
D. the values a and q have the same sign because there is 2 xintercepts.
I chose B, is that correct?
