By inspection 1 is a root of y ,
Hence , (x-1) is a factor of y ,

Hence , the 2 other roots are -1/2 and 3 , and the above graphs confirms the same.
Hope it helps you :)

Answer that’s the answer I think u can use a calculator 7/10
Everyday the number is tripled by 3 and x represents the number of days, which we don’t know, so it would be 3x.
He started with 24.
So the equation is:
24+(3x)
Midpoint formula (x1 + x2) / 2, (y1 + y2)/2
(-2,2)...x1 = -2 and y1 = 2
(3,-1)...x2 = 3 and y2 = -1
now we sub
m = (-2 + 3) / 2 , (2 - 1) / 2
m = (1/2, 1/2) <===
