how to solve graphs in geometry?

To graph equations, you'll have to follow the next
steps:

- you'll have to draw the Cartesian coordinate
system, namely the x horizontal axis and the y vertical axis, which is perpendicular to
x axis at the point (0,0), called the origin of the system of
coordinates.

- write the equation such as y to be isolated
to the left side:

y = ax^n + bx^n-1 +
....

- plug in x values, from the domain of definition of
the function whose equation is y = ax^n + bx^n-1 + .... For each x value will correspond
a y value, such as you'll get specific pair of coordinates
(x,y).

- graph the coordinates counting x units on  the x
axis and y units on y axis and mark these points.

- draw
the graph of the function that passes through all these marked
points.

Note that the curve depends on the type of
expression of the function: if the function is linear, the graph will be a straight line
and if the function is quadratic, the graph will be a parabola.
