what happens when you graph an equation with x3 (x cubed)?

Question

is an equation with x cubed 3 dimensional

Answer 1

Nope, it's 2-d, the same is for quartics and higher degrees.

The reason is b/c it only has two variables, not 3 (a 3-d graph needs an x, y, and z -value for every point).

Answer 2

Nope; try it for yourself.

Let y = x^3. Then start plotting points, the same way that is done with plotting points for x^2 (a parabola) and x (a line).

If x = 0, y = 0^3 = 0
x = 1, y = 1^3 = 1
x = -1, y = (-1)^3 = -1
x = 2, y = 2^3 = 8
x = -2, y = (-2)^3 = -8

Plot the points (0,0), (1, 1), (-1, -1), (2, 8), (-2,8) and connect the dots. This gives you a sense of how the graph looks like.

And, as you can see, it's not three dimensional because all that's involved is getting a y value from an x value.

Answer 3

each y fee has x^3 extra to it. The dip or upward thrust interior the quadratic will in specific circumstances integrate with the wiggle of the cubic to function some wiggles so on occasion the recent curve could have a community minimum and a community maximum. this is extra suitable to discern it out by ability of in basic terms performing some examples of equations that have an x^3 term and then the quadratic, linear, and relentless words. as an occasion x^3 + (x-8)^2 looks different from x^3 + x^2 or x^3 - x^2 and so on.

Answer 4

It would still be a 2-D because you are dealing with the same kind of matrices- just a 2 x 2 because of 2 variables

And it would be a multiple curved line

Answer 5

If the equation contains only two variables, x, y, then it is two dimensional.
If it has three variables, it is three dimensional.
Both are regardless of whether the equation has x^3.

Answer 6

if you want yes and the z = 0

Answer 7

some thing like this " like the letter U but the lift side is down "
