Answer
The exponential function $y=b^x$ has a y-intercept of $(0,1)$ because the y-intercept always has an x-value of 0 (ie. at the y-axis).
When $x=0$, $y=1$, thus $(0,1)$ is the y-intercept.
Work Step by Step
When $x=0$ is substituted into the function:
$y=b^0=1.$
Thus, $(0,1)$ is the y-intercept.
Alternatively, the function can be graphed and $(0,1)$ can be seen to be the point where the graph crosses the y-axis.
