g a chemistry class and a geometry class is 0.18 if a student is taking a geometry class what is the probability that the student is also taking a chemistry class
First, convert the equation to the standard equation of a parabola. -1/4(y+4)=(x-3)^2 ---multiply -4 on both sides y+4=-4(x-3)^2 ---subtract 4 on both sides y=-4(x-3)^2-4 From the equation, we know that the parabola was moved by 3 to the right, because of (x-3)^2. So the axis of symmetry is x=3. Now look at the number in front of (x-3)^2. It is -4. Since it is negative, the parabola opens downwards.
