Question 316573
<font face="Garamond" size="+2">


Absolutely 100% spot on correct.


Here's how to remember this:  Forget the fact that you were taught that *[tex \Large f(x)] is the name of a function.  In point of fact, *[tex \Large f] is the name of the function whereas *[tex \Large f(x)] is the <i>value</i> of the function named *[tex \Large f] when the independent variable has the value *[tex \Large x].  That should make it easy to remember that *[tex \Large f(2)] is the value of the function named *[tex \Large f] when the value of the independent (or input) variable is *[tex \Large 2].

Let *[tex \Large f] be a function defined by *[tex \Large f(x)\ =\ 3x^2].  Find *[tex \Large f(x\ +\ 1)] expressed in simplest terms
