The y intercept is the point where the line passes through on the y-axis.for example on the graph that I showed we can see how the line passes through the 1 on the y-axis. This means 1 is our y-intercept. If you are still confused let me know lol
As for the domain, the only restriction comes from the logarithm. The argument of a logarith must be strictly positive, so we have
As for the range, we have:
- The range of
are all real numbers
- If we change to
we're translating the function horizontally, so the range remains the same
- If we change to
we're stretching the function horizontally, so the range doesn't change
- If we change to
we're translating the function 1 unit up, but the range is already all the real numbers, so it doesn't change.
