Answer:

x ≈ -2.25

Explanation:

Given :
-x -5 = -2^(-x) + 2

To Find : Value of x

Solution:


f(x)=-x-5 -- Black line


g(x) = -2^(-x)+2 --Red line

Plot the given graphs on the graph

Refer the attached graph .

So, the intersection point provides the answer

Intersection point = (-2.248,-2.75)

So, x≈ -2.25

Hence the value of x is -2.25.
