If you're trying to plot the curve y = x2, you can do so by plugging a few small values in as x, finding their corresponding y values, and marking those points on a graph. Then draw a "curve of best fit" that intersects all of those points. This particular curve would be a parabola moving upwards, with a focal point of (0, 0).
No translation will invert a quadratic graph.
the graph is moved down 6 units
x2+(y-x2/3)2=1
y=x2+4x+1
Select two points on the graph and suppose their coordinates are (x1, y1) and (x2, y2) then the gradient = (y1 - y2) / (x1 - x2) provided that x1 and x2 are different. If not, the gradient is not defined.
Rise divided by run. (Y2 - Y1) / (X2 - X1) - with (X1, Y1) and (X2, Y2) being two points on the graph.
The graph is a parabola facing (opening) upwards with the vertex at the origin.
y = (square root 1- x2) + (cube root x2)
you need 2 points on the line y2-y1 slope=----- x2-x1
