A^2-3a+14 is the answer :)
Y=3x^2. -12x+6
If x= 0 then y= 3•0^2 -12•0+6=6
X=0, y=6
y intercept is the place where the curve touches the y-axis and is at point (0, 6)
The value of m is -30 because once you get m on the one side the equation is 3m=-90 and once you divide -90 by 3 you get m=-30.
You need to subtract the rate of decay from 1.
The equation would be 800(1-0.2)^x = 800(0.80)^x
