Answer:
[tex]f(3)=-5[/tex]
Step-by-step explanation:
We have the functions [tex]f(x)=-2x+1[/tex] and [tex]g(x)=4x-5[/tex]
We want to find [tex]f(3)[/tex]. So, we can use our first function.
Substitute 3 for x. This yields:
[tex]f(3)=-2(3)+1[/tex]
Multiply:
[tex]f(3)=-6+1[/tex]
Add:
[tex]f(3)=-5[/tex]
So:
[tex]f(3)=-5[/tex]
