Step-by-step explanation:
Use Pythagorean theorem, C^2 = A^2 + B^2
Where c is the hypotenuse, and b and a are the sides.
Substitute and solve:
X 2^(-x) 4^(x+3)
-3 8 1
-2 4 4
-1 0 16
0 1 64
1 0.5 256
2 0.25 1024
3 0.125 4096
The solution is x = -2 because both functions return the same value, i.e. 4.
