Answer:
[1,2], [2,1], [3,0]
Step-by-step explanation:
To find F-1(x) if F(x)=x+3 we just need to put -x instead of x.
From our graph(attached) we multiply any three solutions by a -1:

Hence, the 3 solutions are [1,2],[2,1],[3,0]
Answer:
h = 12 cm
Step-by-step explanation:
Use the formula for area of a triangle A = (1/2)bh, where b is the base, and h is the height.
Plug in the given information of A = 36, and b = 6, then solve for h
36 = (1/2)(6)h
36 = 3h (one half of 6 is 3 (1/2)(6) = 3 )
12 = h (divide both sides by 3 to isolate h)
