The graph of an exponential function $y=b^{x}$ contains the point $(1,b)$, because $y=f(1)=b^{1}=b$.
We know that the graph of an exponential function $y=b^{x}$ contains the point $(1,b)$, because $y=f(1)=b^{1}=b$. In other words, the exponential function contains this point, because the value of a real number $b$ raised to the power of 1 is equal to $b$.
