For the Pair of Functions, Find the Indicated Sum, Difference $f ( x ) = \sqrt { 2 x + 4 } , g ( x ) = \sqrt { 25 x - 16 }$

Short Answer

For the pair of functions, find the indicated sum, difference, product, or quotient.
- $f ( x ) = \sqrt { 2 x + 4 } , g ( x ) = \sqrt { 25 x - 16 }$
Find (fg)(x)
A) (2 x+4)(5 x-4)
B) $( 5 x - 4 ) ( \sqrt { 2 x + 4 } )$
C) $( \sqrt { 2 x + 4 } ) ( \sqrt { 25 x - 16 } )$
D) (2 x+4)(25 x-16)
