Question 1010991: Draw the graph of y=2x^2+x-2 and y=4-2x for the value of X ranges from -3 to +2.
Use a scale of 2 cm to 1 unit on x axis and 1cm to 1 unit on y axis
Use your graph to find
a) minimum value of y
b) the roots of the equation
c) the value of y for which 2x^2-x-2=0.

graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C2x%5E2-x-2%29
ymin=-2.125
roots=-0.7808, 1.2808
c is 0, that is the value of y for which the equation =0.
