Using a table of values, determine the solution to the equation below to the nearest fourth of a unit.

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

x ≈ 2.25
x ≈ -2.5
x ≈ -2
x ≈ -2.25

Respuesta :

it would be 2.25 b3cause you can't have negatives as a powered to -2

Answer:

x ≈ -2.25

Step-by-step explanation:

Given : [tex]-x -5 = -2^{-x} + 2[/tex]

To Find : Value of x

Solution:

[tex]f(x)=-x-5[/tex]    -- Black line

[tex]g(x) = -2^{-x}+2[/tex]   --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.
