The 1 represents the y intercept so a point is (0,1). To find other points, plug in values for x. For example, plus in x and you get a y value of 2. So just plot a number of points and then connect them with a curved line( called a parabola).

For the equation y = x² + 1, we know the y-intercept is at (0,1) so we need to make a table and graph about 1
x   |   y
-5  |  26        Y = (-5)² + 1      Choose x values and find the y value after multiplying
-3  |  10                                  you can choose any x values you want, just make sure
 0  |    1                                  you have some negatives and some positives in your
 3  |  10                                  table.
 5  |  26

after you make a table with a few negative and positive points...graph

How do I factor 3X^3-19X^2-14X=0?
Novosadov [1.4K]

Just as you look at it, the only factor common to all three terms is 'x'.
So you can factor the 'x' out and make the equation . . .

           x (3x²-19x - 14)  =  0

Right there, that tells you that [ x = 0 ] is a solution of the original equation.

But you're not looking for solutions, you're looking for factors, so you continue.

What about that ugly trinomial:  [ 3x² - 19x - 14 ]  ?  Can that be factored ?

Not easily.  But if you stuff it into the quadratic equation, you'll find two solutions
to the equation
                                 3x² - 19x - 14 = 0

and you'll recall that  (x - a solution) is a factor of the left side.
So you can find the remaining two factors of the original trinomial.
