Answer:
-15
Step-by-step explanation:
The given functions are [tex]f(x)=x^2+1[/tex] and [tex]g(x)=3x+1[/tex]
We want to find [tex]2-f(4)[/tex]
When we substitute x=4 into [tex]f(x)=x^2+1[/tex] we get:
[tex]f(4)=4^2+1[/tex]
We evaluate to get:
[tex]f(4)=16+1[/tex]
This simplifies to
[tex]f(4)=17[/tex]
Therefore [tex]2-f(4)=2-17=-15[/tex]
I am very sure you missed out some important parts of the question because g(x) is not used.
