Question 609176
<font face="Times New Roman" size="+2">


Take whatever is inside the parentheses and put it in place of *[tex \LARGE x], then do the arithmetic.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ 3x^2\ -\ 5x]


So


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(1)\ =\ 3(1)^2\ -\ 5(1)\ =\ -2]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(a)\ =\ 3a^2\ -\ 5a]


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


See?

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
