Question

HELP PLEASE THERES A PIC I PUT IN​

Answer 1

Answer:

(3, 10)

Step-by-step explanation:

f(3) means substitute the value of x = 3 into f(x)

$\implies f(3) = (3 \times 3) + 1 = 10$

Therefore, when x = 3, y = 10

So the ordered pair is (3, 10)

Answer 2

• f^{-1}(x) is of no use here

$\\ \tt\longmapsto f(x)=3x+1$

$\\ \tt\longmapsto f(3)=3(3)+1=9+1=10$

Pair is (3,10)
