Question

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

Answer 1

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

Answer 2

Answer:

x ≈ -2.25

Step-by-step 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.
