First one is 6/15 then .004 then .4%
19 is you awnser since:
By order of operations first do the exponent and then do the multiplication and finally the subtraction
3 to the third is 27
4 times 2 is 8
so 27-8 is 19
3 to the(3)-(4)(2)
27-(4)(2)
27-8
19 is your answer
y = a ( x - h)^2 + v
a is positive when the parabola opens up and negative when it opens down.
I believe the answer is 0=1
