At a function's x-intercept, its y-value is equal to zero. Thus to find our x-intercepts, we need to set the function equal to 0 and solve for .
We raise both sides by e to cancel the logarithm and get:
So our two x-intercepts are at .
The y-intercept of a function occurs when . Therefore the y-intercept is .
