ANSWER

x = 2

EXPLANATION

To find the wrong value we have to find all y-values for the x-values of the table, replacing x with each value in the table,

[tex]\begin{gathered} x=0;y=\frac{3}{4}\cdot0=0\Rightarrow correct \\ x=2;y=\frac{3}{4}\cdot2^2=3\Rightarrow incorrect \\ x=3;y=\frac{3}{4}\cdot3^2=6\frac{3}{4}\Rightarrow correct \\ x=5;y=\frac{3}{4}\cdot5^2=18\frac{3}{4}\Rightarrow correct \end{gathered}[/tex]

Hence, the incorrect value of y is shown for x = 2
