+67 A function is defined as \(f(x)=x^2-3x+4\). What expression can be used to describe \(f(2x)\)? Express your answer in simplified form in terms of x.
So far, I know that my expression that can be used to describe \(f(2x)\) is \(f(2x)=2x^2-6x+4\).
How do I "express my answer in simplified form in terms of x"?
Thank you.
+605 $2x^2-6x+4$ is "in simplified form in terms of $x$".
You're done already!!!!
+33661 If \(f(x) = x^2-3x+4\) then \(f(2x)=(2x)^2-3(2x)+4\) which, when simplified is \(4x^2-6x+4\)
+67 oh wait thank you so much. i totally forgot about the parentheses and didn't distribute the square to the 2 also.
