(2, 2.5) is exactly halfway
The correct answer is C. if you plug zero in for 'x' you will get the y-intercept.
-2(0-2)(0-4)= -2(-2)(-4)=-16
Next set each factor equal to zero to get the x-intercepts.
(x-2)=0 x = 2 (2,0)
(x-4) = 0 x = 4 (4,0)
I hope this helps

Mode-no number repeats itself more than once, therefore there is no mode for this data.
z=(63-84)/3= -21/7= -3
P(x>63)=p(z > -3) = .9987 or 99.87%
