Answer:
It is the graph of y=2x translated 4 units downward
Step-by-step explanation:
Given
[tex]y = 2x[/tex] to [tex]y' = 2x - 4[/tex]
Required
We have:
[tex]y = 2x[/tex]
Subtract 4 from both sides [In other words, shift downward by 4 units]
[tex]y - 4 = 2x - 4[/tex]
This implies that:
[tex]y' = y -4[/tex]
Substitute [tex]y = 2x[/tex]
[tex]y' = 2x -4[/tex]
Answer:
It is the graph of y = 2x translated 4 units downward.
It is the graph of y = 2x translated 2 units to the right.
Step-by-step explanation:
Recall that f(x) β k is a vertical translation that translates f(x) down k units. And, a vertical translation also translates a function horizontally, and vice versa. So, y = 2x β 4 translates the function y = 2x down 4 units. But 2x β 4 is also equal to 2(x β 2), so y = 2x β 4 also describes a translation to the right by 2 units.
