Answer:
-10xsquared-x+38
Step-by-step explanation:
so,
general eqn of quadratic equation is,
axsquared+bx+c=y
where,
x and y are exchanged by coordinates given in qn
1,64a-8b+c=0
2,4a-2b+c=0
or c=2b-4a
60a-6b=0
3,36a-6b+c=8
32a-4b=8
Sub in given values to get 2 equations.

Solve system using elimination. Add the equations together, cancelling out 'b'

Sub into first equation to get value for 'b'
Answer:
C.
Step-by-step explanation:
Integers are rational numbers.
A + B = m/q + n/p = (mp + nq)/pq
(7,0) because that’s where it is crossing the x-intercept
