Sagot :

FIND THE FOLLOWING:

Let:

  • f(x) = x² + 6
  • g(x) = -x + 7
  • h(x) = x² - 9x + 14
  • j(x) = 6x³ + 5x² - 4x + 3.

16.) (f + g)(x) = f(x) + g(x)

  • (f + g)(x) = (x² + 6) + (-x + 7)

  • (f + g)(x) = x² + 6 - x + 7

  • (f + g)(x) = x² - x + 6 + 7

  • (f + g)(x) = x² - x + 13

17.) (j - h)(x) = j(x) - h(x)

  • (j - h)(x) = (6x³ + 5x² - 4x + 3) - (x² - 9x + 14)

  • (j - h)(x) = 6x³ + 5x² - 4x + 3 - x² + 9x + 14

  • (j - h)(x) = 6x³ + 5x² - x² - 4x + 9x + 3 - 14

  • (j - h)(x) = 6x³ + 4x² + 5x - 11

18.) (f • g)(x) = f(x) • g(x)

  • (f • g)(x) = (x² + 6)(-x + 7)

  • (f • g)(x) = -x³ + 7x² - 6x + 42
