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
you need to make the fraction to 100
100/25=
you multiply 20x4
80
When you multiply 10, move the decimal point to the right one place value
3.14 x 10 = 31.4
31.4 is your answer
