Is y2 4 x2 a function?

Is y2 4 x2 a function?

For example, consider the relation x2+y2=4. This is a one-to-many relation because a single x-value relates to two different y-values. Therefore x2+y2=4 is not a function.

What is the center of the circle x2 y2 4?

1 Expert Answer Since the equation for this circle is (x – 0)2 + (y – 0)2 = 4, the center is (0,0) and the radius is √4 = 2.

Is X² y² 9 a function?

Explanation: In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation. and therefore the equation is not a function.

Which is the graph of x2 9 y2 4 1?

If you need any certain explanation: It is a Horizontal Transverse axis graph. The easiest way you can tell is just by seeing that x comes before the y in the equation. Solving it by rewriting it in the form of a standard hyperbola equation you get a=3 and b=2.

How do you know if a line is vertical?

This relationship is always true: a vertical line will have no slope, and “the slope is undefined” or “the line has no slope” means that the line is vertical. (By the way, all vertical lines are of the form “x = some number”, and “x = some number” means the line is vertical.

What is horizontal and vertical?

So, the horizontal line is one that runs across from left to right.

How do you tell if a line is horizontal or vertical?

Since the slope is positive, the line would rise (left to right). Example 2: Find the slope of the straight line that passes through (1, -4) and (-1, 3) or state that the slope is undefined. Then indicate if the line through the points rises (left to right), falls (left to right), is horizontal, or is vertical.
