please show all the steps. answer 20 and 22 only. thank you

Differentiate the function. f (x) = 186.5 4. f(x) = 30 f ( 1) = 2 - 31 6. F(x) = 1x' f (x) = x - 4x + 6 8. f (1) = =10 - 31* + 1 f (1) = (1 + 8 ) 10. h(x) = (x - 2)(2x + 3) 12 A(S) = - 12. B( y) = cy-6 g (1) = 21-3/4 14. h(1) = V1 - 4e' 4 y = 3e* + 16. v = vx (x - 1) Vx F (x) = 4x) 18. /(x) _ - 3x + x 2 x- + 4x +3 V = 20. g(1) = 24 + V3u b 1. y = 47- 22. y = de" + -+
