If you wanted to shift the graph of y = 2x + 5 up, which equation could you use?

y = 2x + 5+2 graph would shift by 2 unit.

Step-by-step explanation:

Given  : y = 2x + 5 .

To find :If you wanted to shift the graph up what would be equation .

Solution : We have given that y = 2x + 5 .

BY the transformation rule ; if f(x) +k then graph would shift up by k units .

Then to shift the graph of y = 2x + 5 up we need to add something in 5

Like   y = 2x + 5+2

Then graph would shift by 2 unit.

Therefore,   y = 2x + 5+2 graph would shift by 2 unit.

f(x) = y

f(-3) = -5
