A. f(x) < 0 on the interval x < 0. b. f (x) > 0 on the interval x < 0. c. f (x) < 0 on the interval 0 < x < 1. d. f (x) > 0 on the interval 0 < x < 1. e. f (x) < 0 on the interval 1 < x < 3. f. f (x) > 0 on the interval 1 < x < 3. g. f (x) < 0 on the interval x > 3. h. f (x) > 0 on the interval x > 3

f(x) > 0 - I and II quadrant

f(x) < 0 - III and IV quadrant

Look at the picture.

A. F(x) < 0 on the interval x < 0.     TRUE

B. F (x) > 0 on the interval x <0.      FALSE

C. F (x) < 0 on the interval 0 < x < 1.      TRUE

D. F (x) > 0 on the interval 0 < x < 1.      FALSE

E. F (x) < 0 on the interval 1 < x < 3.     FALSE

F. F (x) > 0 on the interval 1 < x < 3.      TRUE

G. F (x) < 0 on the interval x > 3.     TRUE

H. F (x) > 0 on the interval x > 3.      FALSE    

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
