we are given a function

First translation:
The graph of function is vertically stretched by a factor of 7
Whenever we vertically stretch any function by 'a' units
so, we can write it as

Here, it is vertically stretch by 7
so, we get


Second translation:
Whenever we reflect any function about x-axis
we multiply y-value by -1
so, we can write it as

Here , it is reflected in the x-axis
so, we can multiply by -1 to y-value
we get
