A function is defined as f(x)=x2−3x+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)=2x2−6x+4.
How do I "express my answer in simplified form in terms of x"?
Thank you.
$2x^2-6x+4$ is "in simplified form in terms of $x$".
You're done already!!!!
oh wait thank you so much. i totally forgot about the parentheses and didn't distribute the square to the 2 also.
