Answer:
B.-6
Step-by-step explanation:
Replace x with 2.
f(x)=3x-12
f(2)=3*2-12
f(2)=6-12
Therefore,f(2)=-6 ans.
Replace x with 2:
f(x) = 3x -12:
f(2) = 3(2) - 12
= 6 - 12
= -6
✿ Domain is the Set of Values of x
⇒ Domain = { 10 , 15 , 19 , 32 }
✿ Range is the Set of Values of y (Images of x)
⇒ Range = { -1 , 5 , 9 }
First Option is the Answer
Answer: y = 2x+8
