a

How do we shift the graph of $y=\frac{1}{x}$y=1x to get the graph of $y=\frac{1}{x}+4$y=1x+4?

Move the graph $4$4 units to the left.

A

Move the graph upwards by $4$4 unit(s).

B

Move the graph downwards by $4$4 unit(s).

C

Move the graph $4$4 units to the right.

D
b

Hence plot $y=\frac{1}{x}+4$y=1x+4 on the same graph as $y=\frac{1}{x}$y=1x.
