The graph of y= |x| is reflected across the x axis and then scaled vertically by a factor of 7 what is the equation of the new graph

Option (B)

Step-by-step explanation:

Given equation of the absolute function is,

y = |x|

When this function is reflected across the x-axis, new equation of the graph will be

y = -|x|

Now the image of the given function has been scaled vertically by a factor of 7,

Therefore, equation of the new graph will be,

y = -7|x|

Option (B) is the correct option.
