Answer:
B. f(-1)=6
C. The domain of f(x) is the set {-2.-1,0,1,2,3,4,5,6}
Step-by-step explanation:
To find f(5) from the table means, the y-value that corresponds to x=5.
This value is 12.
This implies that:
f(5)=12
Also the y-value that corresponds to -1 is 6.
Hence f(-1)=6
The domain of f(x) are the set of all the x-values.
The domain is : {-2.-1,0,1,2,3,4,5,6}
The range for f(x) is the set of all the corresponding y-values.
From the table, the range is: {5,6,7,8,9,10,11,12,13}
