Question

Match each equation with a description of the function it represents.
A f (x) = 2x + 4
B g(x) = 2 (x + 4)
(1) To get the output, add 4 to the input, then multiply the result by 2.
(2) To get the output, add 2 to the input, then multiply the result by 4.
(3) To get the output, multiply the input by 2, then add 4 to the result.
(4) To get the output, multiply the input by 4, then add 2 to the result.
Ch (x) = 4x + 2 h x
D k(x) = 4(x + 2) : + 2​

Answer 1

Answer:

A matches to number 3

B matches to number 1

C matches to number 4

D matches to number 2

Example of the inverse for B:

2 (x + 4) is the same as 2x +8

To make 2(x+4) - with x as the input, to get to 2x+8:

1.First, x must be added to 4 & the same as x+4.

2. Then, multipled by 2 to get 2(x+4) & the same as 2x+8, when expanded.
