Question 78246: my question is plot a graph of the following curves and write down co-ordinates of their intersection with the x- axis
a, y=x²-x-2
b, y=2x²-3x-9
plot these graphs between x=-2 and x=+3
Answer by checkley75(3666) (Show Source): You can put this solution on YOUR website!
y=x^2-x-2
y=2x^2-3x-9
(graph 300x500 pixels, x from -5 to 5, y from -15 to 15, y = x^2 -x -2 and y = 2x^2 -3x -9).
THE QUESTION YOU ASKED WAS FOR THE INTERSECTION WITH THE X AXIS.
THE RED CURVE INTERSECTS THE X AXIS @ (2,0) & (-1,0)
THE GREEN CURVE INTERSECTS THE X AXIS @ (3,0) & (-1.5,0)
