Question

Choose the table that represents g(x) = 4⋅f(x) when f(x) = x − 5

Answer 1

The answer is B

x g(x)

1 −16

2 −12

3 −8

Answer 2

Answer: (b)
x g(x)
1 -16
2 -12
3 -8


If g(x) is 4*f(x), then we can find g(x) by multiplying 4 by x-5

g(x) = 4(x-5)
= 4x-20

Now we can plug in 1,2, and 3 for x to see which table makes sense.
g(1) = 4(1) - 20
= -16

g(2) = 4(2) - 20
= -12

g(3) = 4(3) - 20
= -8
