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

Question

x	g(x)
1	−4
2	−3
3	−2

x	g(x)
1	−16
2	−12
3	−8

x	g(x)
1	−20
2	−18
3	−16

x	g(x)
1	−1
2	−2
3	−3

Answer 1

4f(x) means to multiply the entire f(x) function by 4.

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

Can you tell which x values plugged into 4x-20 produce the correct y values in your table?
