Explanation:

Just took it right now

Answer 2

Option (d) and (e) is correct.

Graph is shifted down and vertically stretched

Step-by-step explanation:

Given : The exponential function
`f(x)=2^x` undergoes two transformations to
`g(x)=5\cdot 2^x-3`

We have to choose the how the graph changes.

Consider the given exponential function
`f(x)=2^x`.

Vertically compressed or stretched

For a graph y = f(x),

A vertically compression (stretched) of a graph is compressing the graph toward x- axis.

• if k > 1 , then the graph y = k• f(x) , the graph will be vertically stretched by multiplying each y coordinate by k.

• if 0 < k < 1 if 0 < k < 1 , the graph is f (x) vertically shrunk (or compressed) by multiplying each of its y-coordinates by k.

• if k should be negative, the vertical stretch or shrink is followed by a reflection across the x-axis.

Here, k = 5

So the graph will be vertically stretched

Also, Adding 3 to the graph will move the graph 3 units down so, the graph is shifted down.

So, The graph is shifted down.
