F(x)=(7x-2)(5x-8)(x+5)(x-6) has zeros at x=-5, x=2/7, x=8/5, and x=6. What is the sign of f on the interval -5
Choose 1
(A) f is always positive on the interval.
(B) f is always negative on the interval.
(C) f is sometimes positive and sometimes negative on the interval.

i hope this is what you were looking for.

see attached graph

could you provide figure.

none.

step-by-step explanation:

6

b=-6

compare the slopes

m

m of the two equations.

m

=

5

,

m

2

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

=

0

m1=5,m2=0

493 would be the correct answer
