Write 2x+3(to the power of 2)+x-4(to the power of 2). Then do the equations and you should get 4x+9+2x+16. Combine like terms and that's your answer. I know it might be weird that it's not like 72 or something, but it's math haha. Your answer should be 6x+25! Make sure you understand this before just writing all of this down. Also, don't be afraid to ask your teacher. They are there to help!

<h3>Functions and values</h3>
Given the following function expressed as:
f(x) = 1/2(x)
We are to determine the value of f(7.6). Substitute x = 7.6 into the function as shown:
f(7.6) = 1/2(7.6)
f(7.6) = 7.6/2
f(7.6) = 3.8
Hence the value of the function f x is 7.6 is 3.8
