Question: x intercepts = (6,-1) a= -1 b = 5 c=6
The roots are the sames as the x intercepts. for a quadratic function the sums of roots = -b/a
the product of the roots = c/a
for the graphed function
a) write the value of -b/a and use this to express b in terms of a.
b) write the value of c/a and use this to express c in terms of a
Edit
Answer: a) write the value of -b/a and use this to express b in terms of a.
-b/a=-5/-1=5(ans.)
b) write the value of c/a and use this to express c in terms of a.
c/a=6/-1=-6(Ans.)
