F(x)=-x+2
y=-x+2
x=-y+2
Solve for y
x-2=-y
-y/-1=(x-2)/-1
y=-x+2
So f^-1(x) is gonna be -x+2
Answer:
because it's a ringt angle triangle
90°
It is decreasing because the y value decreases from left to right
We grapht hem
we see that the base is from (-2,2) and (6,2), 8 units long
the height will be from y=2 to y=8 or 6 units
so then, the area=1/2 times base times height=1/2 times 8 times 6=24 square units
