Factor the gcf:
-4y^2 + 12y - 16
a.) -1(4y^2-12y+16)
b.) -4y(y^2-3y+4)
c.) -(y^2-3y+4)
d.) -4(y^2+3y-4)

up

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
