It's just tricky to input it in my calculator
Your calculator most likely has the button 'log' implying base 10 or 'ln' implying base e. Here is a property that will help you graph logarithmic functions with different bases:
where c can be any number.
Since your calculator probably deals with base 10 and e, those are the values you will use for c, i.e.:
ALL log graphs of the form (a > 1) look like the one below. they all pass through the point (1,0), and are asymptotic to the y-axis, and have domain .
with your graph, you are shifting the log up by 4 units (standard transformation rule when you add a positive constant).
now, this shift may affect the intercepts. in this case, it affects the x-intercept only. no worries, you can calculate the new intercept.
for the x-intercept, set y = 0 in your function and solve for x. then just draw a curve that looks like the one below, but instead of passing through (1,0), it passes through the new x-intercept you found.
