Let
\(f(x) &= 2x + 5 g(x) &= √{f(x)} - 2 h(x) &= f(g(x)) \)
What is
\( h(2)\)?
f(x) = 2x + 5
g(x) = √[ f(x) ] - 2
h(x) = f(g(x))
h(2) = f(g(2))
g(2) = √[ f(2) ] - 2
f(2) = 2(2) + 5 = 4 + 5 = 9
g(2) = √[ f(2) ] - 2 = √[ 9 ] - 2 = 3 - 2 = 1
h(2) = f(g(2)) = f( 1 )
f(1) = 2(1) + 5 = 2 + 5 = 7
h(2) = f(g(2)) = f( 1 ) = 7
