Answer:
[tex]f(3)=-1[/tex]
Step-by-step explanation:
Given equation is:-
[tex]f(x)=-\frac{2}{3}x+1[/tex]
To find [tex]f(3)[/tex] we need to substitute 3 in place of x in the above equation i.e. [tex]f(x)=-\frac{2}{3} x+1[/tex]
After substituting 3 in place of x we get,
[tex]f(3)=-\frac{2}{3}\times (3)+1[/tex]
[tex]f(3)=-2+1[/tex]
[tex]f(3)=-1[/tex]
Therefore for function [tex]f(x)=-\frac{2}{3}x+1,\ f(3)=-1[/tex]
