Hi i am new here, and just wondering if my answers are right, please check for me.(adsbygoogle = window.adsbygoogle || []).push({});

1. Evaluate g(x) = x^2 + x

g(x + 3)

my answer: x^2 + 7x -12

2. Function or not:

x^2 = y - 3

I say not a function.

3. y^2 = x - y

I would say yes this is a function.

thanks a lot
