Question

Does anyone know how to solve this??

Answer 1

I think we are doing the same assignment

Answer 2

a) (f + g)(x) = x² - 2x + 3x - 4 = x² + x - 4

domain: x E R

b) (f - h)(x) = x² - 2x - ( - 2x + 1) = x² - 1

domain: x E R

c) (f.g)(x) = (x² - 2x)(3x - 4) = 3x³ - 10x² + 8x

domain: x E R

d)

`( (h)/(f) )(x) = \frac{ - 2x + 1}{x {}^(2) - 2x}`

domain: x E R\{0; 2}
