Question 250186
<font face="Garamond" size="+2">


Simply substitute whatever is in the parentheses in place of the independent variable and do the arithmetic:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ x^2\ -\ 3]


So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(3)\ =\ (3)^2\ -\ 3]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(1,589,628)\ =\ (1,589,628)^2\ -\ 3]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(a)\ =\ (a)^2\ -\ 3]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f\left(\frac{r^2s}{w^3\sqrt[14]{z^5}}\right)\ =\ \left(\frac{r^2s}{w^3\sqrt[14]{z^5}}\right)^2\ -\ 3]
