Question 909158
when m = 2,  we have y = -x^2 -2x -1
when m = -6, we have y = -x^2 +6x -9
the above are two equations of parabolas that curve downward
a) y = -x^2 -2x -1 factors into (-x-1) * (x+1) and
x intercept is -1
y intercept is -1
b) y = -x^2 +6x -9 factors into (-x+3) * (x-3) and
x intercept is 3
y intercept is -9
c) for each triangle the base is 4 units
Area (A) of triangle is (1/2)*base*height
for a) A = (1/2)*4*1 = 2
for b) A = (1/2)*4*9 = 18
