Question 1164683
<font face="Times New Roman" size="+2">


Write out *[tex \Large f(x)\ =\ 2x^2\ -\ 5x\ +\ 7] in pencil.


Erase each instance of *[tex \Large x] and replace it with a *[tex \Large (2)]


Do the indicated arithmetic.


*[tex \Large f] is a function.  *[tex \Large f(x)] means "the value of the function *[tex \Large f] at *[tex \Large x]".  So *[tex \Large f(2)] means "the value of the function *[tex \Large f] at 2".
