Answer
r = -20
Step-by-step explanation
4r-8=5r+12
subtract 4r from both sides of the equation
-8=r+12
subtract 12 from both sides of the equation
-20 = r

Hope It helps!!!!
The domain is the value of x, the range is the value of y.
A parabola opens infinitely to the right and left, so x can be any number, the domain is all real numbers
Vertically, however, a parabola opens only one way, either upward or downward. when it opens upward from a a certain level, say, the lower point (the vertex) has a y coordinate of 2, we say the range is all real numbers larger than or equal to 2, or y≥2. When it opens downward, we say the range is all real numbers smaller or equal to 2, y≤2
