Answer:

Solution is:

x ≈ 2.25

Explanation:

The solution of the equation
3^(-x + 2) = 2^x - 4 is that point on the graph at which the two graphs i.e. graph of
3^(-x + 2) and
2^x-4 meet

As we can clearly see the two graphs meet at:

(2.251,0.759)

Hence, Solution is:

x ≈ 2.25

Solve the equation for x by graphing. 3^(-x + 2) = 2^x - 4 x ≈ 3 x ≈ 2.25 x ≈ 1.25 x-example-1
