Question 310087: Please help me with this problem. f(x)= x(squared)-5x+4/x(squared)-4.
Find f(2). Express the domain of "f" using interval notation.
I don't understand this problem. When it says f(2), does it mean substitute all the x's in the equation as 2's?

You can put this solution on YOUR website!
f(x)= x(squared)-5x+4/x(squared)-4
f(2)=2^2-5*2+4/2^2-4
f(2)=4-10+4/4-4
f(2)=4-10+1-4
f(2)=-9 ans.
