Homework Help: trig

Posted by y912f on Friday, November 14, 2008 at 11:25am.

can you please show me in steps how to find f(1+a)
in this equation
f(x)=-2x^2+4x+6
i know that you will plug in 1+a anywhere there is x. but after that i get confused.

also can you tell me how to find the domain and range of a relation
for ex. 2x+5y=10
thanks for your help!
