Question 1136628
as x gets more negative, 2-x gets more positive, therefore the function will be positive on the left.


ax x gets more positive, 2-x gets more negative, therefore the function will be negative on the right.


that's because the exponent is odd.


if the exponent were even, like (2-x)^8, then the function would be positive on both ends.


here's what the functions look like.


first (2-x)^7, then (2-x)^8
