Answer:

The required result is 5 unit vertically shifted downward and
(\pi)/(2) unit horizontally shifted left.

Explanation:

Given : Graph
f(x) = 6\sin(2x+\pi)-5

To find : In what direction and by how many units is the graph vertically and horizontally shifted?

Solution :

Vertically shift is up or down,

Vertically shifting down is shifting outside the function,

i.e, f(x)→f(x)-b

In the given graph, The graph is 5 unit vertically shifted downward as


f(x) = 6\sin(2x+\pi)-5 i.e, 5 unit shifted downward.

Horizontal shift is either left or right,

Horizontally shift left is shifting inside the function,

i.e, f(x)→f(x+b)

We can write the given function as
f(x) = 6\sin(x+(\pi)/(2))-5

In the given graph, The graph is
(\pi)/(2) unit horizontally shifted left as


f(x) = 6\sin(x+(\pi)/(2))-5 i.e,
(\pi)/(2) unit shifted left.

Therefore, The required result is 5 unit vertically shifted downward and
(\pi)/(2) unit horizontally shifted left.
