Answer 1

x = 2

Step-by-step 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,

`\begin{gathered} x=0;y=(3)/(4)\cdot0=0\Rightarrow correct \\ x=2;y=(3)/(4)\cdot2^2=3\Rightarrow incorrect \\ x=3;y=(3)/(4)\cdot3^2=6(3)/(4)\Rightarrow correct \\ x=5;y=(3)/(4)\cdot5^2=18(3)/(4)\Rightarrow correct \end{gathered}`

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