Question

May I get help for 4,5,6

Answer 1

4. 11

5. -11

6. ± 5

Explanation:

4. (g - h)(x) = x² - 1 - ( -2x +3) = x² - 1 + 2x -3 = x² +2x -4

(g - h)(3) = 3² + 2.3 - 4 = 9 + 6 - 4 = 11

5. (h-g)(x) = -2x + 3 - (x² - 1) = -2x + 3 - x² + 1 = -x² - 2x + 4

(h-g)(3) = -3² - 2(3) + 4 = -9 -6 +4 = -11

6. g(x) = 24

24 = x² - 1

x² = 24 + 1 = 25

x = √25 = ± 5
