Multiple Choice

Give the equation of the function g whose graph is described.
-The graph of $\mathrm { f } ( \mathrm { x } ) = \mathrm { x } ^ { 2 }$ is vertically stretched by a factor of 8 , and the resulting graph is reflected across the $x$ -axis.

A) $g ( x ) = - 8 x ^ { 2 }$
B) $g ( x ) = ( x - 8 ) ^ { 2 }$
C) $g ( x ) = 8 ( x - 8 ) x ^ { 2 }$
D) $g ( x ) = 8 x ^ { 2 }$
