graph, find x and y intercepts and test for symmetry x=y^3
To Graph:
Create a table of ordered pairs to get a sense of what the graph looks like.
You could begin your table with a few values for x or y. For instance,
y | -2 -1 0 1 2
x | _ _ _ _ _
Now to complete the table, substitute the values for y into the equation, and solve for x. For y = -2, substituting -2 for y in the equation gives
x = (-2)^3, and simplifying this gives x = -8. Now adding this value for x to the table gives
y | -2 -1 0 1 2
x | -8 _ _ _ _
After completing the rest of the table, it should look like this
y | -2 -1 0 1 2
x | -8 -1 0 1 8
and we now can graph the pairs (-8,-2), (-1,-1), (0,0), (1,1), (8,2). Plot these ordered pairs, and you may get an idea of what the graph looks like.
If more pairs are needed it is simply a matter of repeating the process for other values to get enough pairs to recognize the graph.
x and y-intercepts:
Find the x-intercept by substituting 0 for y in the equation and solving for x. The resulting ordered pair(s) will have the form (_,0), and they are your x-intercept(s).
Find the y-intercept by substituting 0 for x in the equation and solving for y. The resulting ordered pair(s) will have the form (0,_), and they are your y-intercept(s).
