The given parabola will open; Down
<h3>How to interpret a parabola curve?</h3>
In parabolic curves, if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
Now, we are given the equation of the parabola s;
-36y = x²
divide both sides by -36 to get;
y = -x²/36
From the above it is clear that the leading coefficient is less than zero and as such the parabola will open in the downward direction.

Answer: Yes, those sides form a right triangle</h3>
===================================================
Work Shown:
a^2+b^2 = c^2
15^2+20^2 = 25^2
225+400 = 625
625 = 625
Since the last equation is true, this makes the first equation true for those a,b,c values. Therefore, by the pythagorean theorem converse, this is a right triangle.
Side note: c is always the longest side.
Answer:
-2, 2, 6
Step-by-step explanation:
f(-4)= -4+2=-2
f(0)=0+2=2
f(4)=4+2=6
Substitute x for the number in parentheses
Their radii, their diameters, their circumference, and their area will all be proportionate. But I think that all circles are proportionate.
