Question

the table represents the function f(x)=2x + 1. which value goes in the empty cell? 23 8 5 3

Explanation:

Step1: Determine the pattern

The function is \( f(x)=2x + 1 \).

Step2: Calculate the value for \( x = 2 \)

Substitute \( x = 2 \) into the function: \( f(2)=2\times2 + 1=4 + 1 = 5 \).

Step3: Verify the pattern with other values

For \( x=0 \), \( f(0)=2\times0 + 1 = 1\) (not in the table but for verification). For \( x = 5\), \( f(5)=2\times5+1=11\). For \( x=-3\), \( f(-3)=2\times(-3)+1=-6 + 1=-5\).
