g(x) = √x
Plug in 16 for x .
g(16) = √16
g(16) = 4
And...
t(x) = 3 - g(x)
Since g(x) = √x , we can substitute √x in for g(x) .
t(x) = 3 - √x
Plug in g(16) for x .
t(g(16)) = 3 - √[ g(16) ]
Since g(16) = 4 , we can substitute 4 in for g(16) .
t(g(16)) = 3 - √[ 4 ]
t(g(16)) = 3 - 2
t(g(16)) = 1
Also...
t(g(16)) = 3 - g( g(16) ) = 3 - g( 4 ) = 3 - 2 = 1
g(x) = √x
Plug in 16 for x .
g(16) = √16
g(16) = 4
And...
t(x) = 3 - g(x)
Since g(x) = √x , we can substitute √x in for g(x) .
t(x) = 3 - √x
Plug in g(16) for x .
t(g(16)) = 3 - √[ g(16) ]
Since g(16) = 4 , we can substitute 4 in for g(16) .
t(g(16)) = 3 - √[ 4 ]
t(g(16)) = 3 - 2
t(g(16)) = 1
Also...
t(g(16)) = 3 - g( g(16) ) = 3 - g( 4 ) = 3 - 2 = 1
