For questions 16- 19, use the functions f(x) = -x² + 8x - 11, g(x) = 14 - 2/3x,

and h(x) = -x - 7.

16. f(-4) - f(1) = ​ (a)  

17. g(9) + h(-14) = ​ (b)  

18. h(8) - 2 times f(3) = ​ (c)  

19. 1/2g(-6) + f(-2) = ​ (d)

Match the following

• 23. Given g(x) = -3/2s - 9, if g(x) = -48, find x.

• x = 3

• 20. given f(x) = 2x + 9, if f(x) = 15, find x.

• x = 32

• 22. Given p(x) = x+7/3, if p(x) = 13, find x.

• x = 26

• 21. Given h(x) = -x - 14, if h(x) = -2, find x.

• x = -12

For questions 24 - 27, use the graph provided.

24. Find f(-1) = ​ (a)  

25. Find f(4) = ​ (b)
