Question

the table represents the function f(x)=2x + 1.

x	f(x)
-3	-5
2
5	11
8	17

which value goes in the empty cell?
o 3
o 5
o 8
o 23

Explanation:

Step1: Substitute x = 2 into function

Given $f(x)=2x + 1$, when $x = 2$, we calculate $f(2)$.

Step2: Perform the arithmetic

$f(2)=2\times2+1=4 + 1=5$.

Answer:

5
