In the given figure, each box represents a function machine. A function machine illustrates what it does with the input.Which of the following statements is correct?

$z=2 x+3$

$z=2(x+3)$

$z=\sqrt{2 x+3}$

$z =\sqrt{2( x +3)}$

Solution

(c)

As the figure gives us the idea to first double the output which will be $2 x$ and then add $3$ , now function will be like $2 x+3$. Now as the figure states to square root of the input which will like $\sqrt{2 } x+3$. so, output $(z)=\sqrt{2 } x+3$
