The answer is D. You’d need to minus the area of the circle away from the area of the triangle to get the area of the shaded region
Y is directly proportional to x and therefore takes the form y=kx where k is the constant of proportionality.
Dividing both sides by x for the given values, k becomes 18/4 = 4.5
3x2+4x=2
6+4x=2
-6 -6
4x=-4
4 4
x=-1
