How to find domain and range of a parabola?

german

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

40.32 is 76.8% of what number?

julsineya [31]

Hey there

Lets solve this question together,

Convert 76.8% to a decimal.

$0.768 * x=40.32$

Multiply 0.768 by x to get 0.768x.

$
0.768x=40.32$

Multiply each term by 1 / 0.768 and simplify.

Cancel the common factor of 0.768.

$x=40.32 / 0.768$

Divide 40.32 by 0.768 to get 52.5

 $x=52.5$
