    Answer:

    option A

    Step-by-step explanation:

    y = k . f( x )

    • if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically stretched by multiplying each of its y-coordinates by k.

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

    • if k < 0, the vertical stretch or shrink is followed by a reflection across the x-axis.

    Given g(x ) = – |x |

                    = -1 × f(x)

    k < 0 , therefore the graph g (x) is a vertical shrink ( or compression ) of graph f
