F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
