Question

s

Answer 1

see its (-3,0) and (2,0) at axis axis, means this are the roots.
(x-a)*(x-b)=0=y------- y here is zero as the graph is on s axis.
where a and b are the roots.
try now.

Answer 2

no it is.
y=(x+3)*(x-2)=x^2 =x -6

Answer 3

sorry
y=x^2+x-6

Answer 4

oh im sorry.
see the equation of quadratic graph is
Y = aX^2 +bX + c
we have points (-2,0), (3,0) and (0,3)
so put this into equation.
you have
3=c ------(1)
0= 4a -2b + c --------(2)
0= 9a +3b + c --------(3)
solving this equations will give
\[Y= (-X^2/2) + (X/2) + 3\] this is according to the graph and not according to your question.
