Please please need help on these two

Answer:

( f + g ) (x) = $2 x^{2} + x - 4$

g(x) - f(x) = $x^{2} - 2 x - 4$

Step-by-step explanation:

f(x) = 4 x - 4 and g(x) = $2 x^{2} - 3 x$

( f + g ) (x) = f(x) + g(x)

= $4 x - 4 + 2 x^{2} - 2 x$

= $2 x^{2} + x -4$

2. g(x) = $x^{2} + 1$ and f(x) = 2 x + 5

g(x) - f(x) = $x^{2} + 1 - (2 x + 5)$

= $x^{2} + 1 - 2 x - 5$

= $x^{2} - 2 x - 4$
