Make tables to find the solution to 4^−x = 2^x + 3. Take the integer values of x between −3 and 3.

Respuesta :

Answer:

the solution is at -1 which is 4.

Step-by-step explanation:

We have been given two functions:

[tex]4^{-x}\text {and} 2^{x+3}[/tex]

We need to take x between -3 and 3

x           [tex]y_1=4^{-x}[/tex]         [tex]y_2=2^{x+3}[/tex]

-2              16                        2

-1                4                        4

0                 1                        8

1                 1/4                      16

2                1/16                     32

Solution is that point where these two function will give same value.

So, the solution is at -1 which is 4.
