HELP PLEASE THERES A PIC I PUT IN

Answer:
(3, 10)
Step-by-step explanation:
f(3) means substitute the value of x = 3 into f(x)
[tex]\implies f(3) = (3 \times 3) + 1 = 10[/tex]
Therefore, when x = 3, y = 10
So the ordered pair is (3, 10)
[tex]\\ \tt\longmapsto f(x)=3x+1[/tex]
[tex]\\ \tt\longmapsto f(3)=3(3)+1=9+1=10[/tex]
Pair is (3,10)
