use a graph to find the zeros of the function f(x)= 2^x - 5

The graph of the function \( f(x) = 2^x - 5 \) crosses the x-axis at approximately \( x = 2.32 \). This is the zero of the function, meaning \( f(2.32) = 0 \).

Would you like more details on how to solve this equation algebraically, or do you have any other questions?
