Ineed 5-7 and i need all the possible work shown. the first one to answer will get you

5. range:(-1.2,0,1,1.2,3,4)
 domain:(-2,-1.2,1.2,2,3,4)

6. the values of the range are all the positive numbers: 0,7,9,12,21
the values of the domain are all the negative numbers: -12,-3

7. the following answers are false for f(x): f(1)=13, f(-9)=88, f(5)=-40

143 75 107 13 the answer
