Question

Can someone please help me with my math homework?

These are the questions:

1. Given f(x) = x2 – 4x – 2 and g(x) = 2x2 + 4x + 9, find (f – g)(x)

2. Given f(x) = 7x – √2 and g(x) = x + √2, find (f + g)(x)

3. Given f(x) = 7x – √2 and g(x) = x + √2, find (f – g)(x)

4. Given f(x) = 3x + 3 and g(x) = 2x – 7, find (gf)(x)

5. Given f(x) = 120x2 – 17x + 1 and g(x) = 119x2 + 16x – 2, find (f – g)(x)

6. Given f(x) = x + 2 and g(x) = x2 – 4, find the function (g/f)(x)

7. Given f(x) = 3x + 3 and g(x) = x2 + 11x – 7, find (gf)(x)
