What is the effect on the graph of the function f(x) = x when f(x) is replaced with -1/2 f(x)?
inn [45]

Answer:

The correct option is B.

Step-by-step explanation:

The given function is

f(x)=x

The new function is

g(x)=-\frac{1}{2}f(x)

g(x)=-\frac{1}{2}x        .... (1)

It is in the form of

g(x)=mx                   .... (2)

Where, m is a constant.

If m is negative, then there is a vertical reflection over x-axis. If the constant is greater than 1, we get a vertical stretch and  if the constant is between 0 and 1, we get a vertical compression.

From (1) and (2), we get

m=-\frac{1}{2}

Since the value of m is negative and absolute value of m is between 0 and 1, therefore the graph g(x) shows the vertical reflection over x-axis and vertical compression.

Option B is correct.
