Answer:

(2,4)

Step-by-step explanation:

substitute the y = 2x for the y in x = -y + 6

x = -(2x) + 6

x = -2x + 6

3x = 6

x = 2

next take x = 2 and input it into y = 2x

y = 2(2)

y = 4

so if x =2 and y = 4, the ordered pair solution is:

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}
