If you want to do it by hand, you can write the equation
.. y = ax^2 +bx +c
and substitute three of the given points. Then solve the resulting three linear equations for a, b, and c.
.. 4 = a +b +c
.. 7 = 4a +2b +c
.. 12 = 9a +3b +c
Subtracting the first equation from the other two reduces this to
.. 3 = 3a +b
.. 8 = 8a +2b
The latter can be divided by 2, so reduces to
.. 4 = 4a +b
Subtracting the first of the reduced equations from this, you have
.. 1 = a
so
.. 3 = 3*1 +b
.. 0 = b
and
.. 4 = a + b + c = 1 + 0 + c
.. 3 = c
And your equation is
.. y = x^2 +3 . . . . . . as shown previously
Answer:
h = 10 bc 4.7 x 10 = 47
f = 36 bc 6 x 36 = 216
g = 3.5 bc 3.5 + 1.6 = 5.1
unlock number equation = f - g x h or 36 - 3.5 x 10

Answer:
x = i√3, -i√3
Step-by-step explanation:
Simply take the root of both sides, then solve.
Answer:
find y intercept: x= 0 => y = 12
y = -x + 12 (1)
y = x + 12 (2) is answer
