ax^2+by^2=k is an ellipse this is not in standard form which is x^2/a^2+y^2/b^2=1 but you will often see ellipses written this way. ellipses are also commonly written in their parametric form which is x=ccos(t) and y=dsin(t). finally a circle is a special case of an ellipse and if a b or k are 0 or negative it is not an ellipse. c and d can be positive but not 0.

What does a nonlinear graph look like?
any graph that is not represented by a line,ie: parabola, hyperbola, circle, ellipse,etc
Is a graph of a quadratic function always a parabola?
No. It can also be a circle, ellipse or hyperbola.
How can you tell if a point is on a graph?
There is a dot on the graph
What does the graph tell us?

How do you do an ellipse graph?
As you may or may not be aware, there are multiple co-ordinate systems by which a graph may be defined. An ellipse graph has the general equation in the following systems:Cartesian (what most people are used to): (X-H)^2 (Y-K)^2---------- + ----------- = 1 (A,B,H,K are constants) A^2 B^2Polar: r(θ)= sqrt( (bcos(θ))^2+(asin(θ))^2 )Parametric: x = a cos(t) , y = b sin(t)
How can you tell if the graph of an equation in the form ax2 plus by2 equals c is a circle or an ellipse?
If a = b then it is a circle; otherwise it is an ellipse.
Is an oval a graph of a function?
No, the graph of an oval/ellipse is not a function because it does not pass the vertical line test.
What happens to the graph of an ellipse when y is replaced by y plus 6?
The whole ellipse shifts down by 6 units.
What does a nonlinear graph look like?

Is a graph of a quadratic function always a parabola?
No. It can also be a circle, ellipse or hyperbola.
How do you write a beginning in short story plot graph?
you tell what you are going to write about in short sentences.
How can you tell if a point is on a graph?
There is a dot on the graph
Is the graph of an ellipse a function?
Yes. It's the graph of [ Y = f(X) ] described by (X/A)2 + (Y/B)2 = C2 A, B, and C are constants. If 'A' and 'B' are both '1', then the graph is a circle with radius 'C'.
Which shape is ellipse?
Ovallike an egg.hey how did u create that question please tell me^ that is so not the answer -.- An ellipse is an oval with a line going down the middle and a line going across. thatd make it look like a square (kinda) inside the oval :D
Where is x axis and y axis on a graph?
The y axis is going up on the graph and the x axis is going sideways on the graph
Why is it necessary to title a bar graph?
to tell them why you made this graph
What are the similarities between a line graph circle graph and bar graph?
First they all tell you the percentages of something and they tell you peoples opinion on things.
