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

the solution is at -1 which is 4.

Step-by-step explanation:

We have been given two functions:

We need to take x between -3 and 3

x                  

-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.

C. f(x) has a double at x=1
