Question

Where is the f(x) negative

a) (0,-6)
b) (-10,7)
c) (-10,0)
d (-7,10)


F(0)=
a) -2
b) 10
c) 7
d) -6


If F(x)=0, find x
a) -2
b) -4
c) 0
d) 7



What is the domain of F(x)?
a) (-10,8)
b) (-6,2)
c) (-10,-7,-2,-1,4,8)
d) (-7,-6,-2,2)

Answer 1

1. a) (0,-6)

2. d) f(0)=-6

3. d

4. a (?)

Explanation:

1. f(0)=-6, which is negative

2. f(0)=-6

3. when x=7, f(7)=0

4. domain: [-10,8] because x=-10 and 8 are included in the domain

Hopefully, this helps.
