How do I find the basic function of:
t(x)= -(-1-x)^2

----------------
The basic function is y = x^2
You could simplify t(x) as follows:
t(x) = -(-(x+1))^2
t(x) = -(x+1)^2
----
Now you can see the x+1 shifts y= x^2 one unit to the left.
---
The negative sign reflects y=(x+1)^2 in the x-axis.
-----
You end up with an upside-down parabola that was shifted one unit to the left:
