Question

The graph of y = - f(x) is the reflection of the graph of f about the ---------------- axis ​

Answer 1

The graph of y = - f(x) is the reflection of the graph of f about the x axis ​

Step-by-step explanation:

The graph of y = - f(x) is the reflection of the graph of f about the ---x--------- axis ​

y = f(x)

y = -f(x)

hence for a point ( x , f(x) ) reflection is  (x , -f(x))

=> ( x , - y)  is reflection of ( x , y)

When reflected through x axis then  x values remain same and sign of y  get changed.

When  reflected through y axis then  y  values remain same and sign of x   get changed.  

y = f(-x)   is reflection around y axis.

The graph of y = - f(x) is the reflection of the graph of f(x) about the ------x--------- axis ​
