\"Given two functions f(x)=2x-5 and g(x)=x^2. Are the following statements true or false. Could you explain as to how you got the answer. And if my answers are correct.

\n" ); document.write( "\n" ); document.write( "f(x) = 2x - 5 and g(x) = x^2
\n" ); document.write( "on c) and d) you are subsituting in values for x
\n" ); document.write( "a) f(x) + g(x) = g(x) + f(x) = 2x - 5 + x^2 = x^2 + 2x - 5
\n" ); document.write( "true, just rearranging terms
\n" ); document.write( "b) f(x) - g(x) = 2x - 5 - x^2
\n" ); document.write( " g(x) - f(x) = x^2 - 2x + 5
\n" ); document.write( "false, 2 different results
\n" ); document.write( "c) f(2) + f(3) = 2(2) - 5 + 2(3) - 5 = 4 - 5 + 6 - 5 = 10 - 10 = 0
