Answer:
we conclude that at x = -2 and x = -1, the value of f(x) = 2⁻ˣ and g(x) = -2x is the same.
Therefore, the solution to f(x) = g(x) is:
x = -2
x = -1
Explanation:
Given the table
x f(x) = 2⁻ˣ g(x) = -2x
-3 8 6
-2 4 4
-1 2 2
0 1 0
1 1/2 -2
2 1/4 -4
3 1/8 -6
If we carefully observe, we can determine that
at x = -2, the value of f(x) = 2⁻ˣ and g(x) = -2x is the same.
In other words,
at x = -2
Thus,
at x = -2
f(x) = g(x)
Also at x = -1, the value of f(x) = 2⁻ˣ and g(x) = -2x is the same.
In other words,
at x = -1
Thus,
at x = -1
f(x) = g(x)
Summary:
Thus, we conclude that at x = -2 and x = -1, the value of f(x) = 2⁻ˣ and g(x) = -2x is the same.
Therefore, the solution to f(x) = g(x) is:
x = -2
x = -1
