The expression obtained is (f + g)(x) = 4x³ - 2x² +6x +1
A function is a law that connects two variables , a dependent and an independent variable.
It comes with a defined range and domain.
It is given that there are two expression
ƒ(x) = 3x² + 6x - 5
g(x) = 4x³-5x² +6
it has been asked to find (f+g)x
so (f + g)(x) = 3x² + 6x - 5 + 4x³-5x² +6
(f + g)(x) = 4x³ - 2x² +6x +1
Therefore the expression obtained as 4x³ - 2x² +6x +1 .
