[tex]f(x)=2x-1[/tex][tex]g(x)=x+4[/tex]
To find the value of:
[tex](g\circ f)(2)[/tex]
We calculated the value of g in function of (f(2)), as follow:
We need first find the value of the f(2):
[tex]f(2)=2(2)-1=4-1=3[/tex]
Then we use this value to evaluate the g(f(2))
[tex](g\circ f)(2)=g\lbrack f(2)\rbrack[/tex][tex]g(3)=(3)+4[/tex]
Then:
[tex](g\circ f)(2)=7[/tex]
