Question 1163503
<font face="Times New Roman" size="+2">


Since 4 is not greater than 4, ignore the *[tex \Large x^2\ -\ 3] piece of the piecewise function.


The *[tex \Large f(x)\ =\ \log(x\,-\,3)] piece of the piecewise function applies because 4 is indeed less than or equal to 4.


Write the applicable piece of the function in pencil and then every place you see an *[tex \Large x], erase it an write a 4 in its place.


Then do the arithmetic.  Hint: *[tex \Large \log_b(1)\ =\ 0\ \forall\ b\ \in\ \mathbb{R}^+]
