1 of 6

Given that the initial inputs of the functions are $2$, $-5$, $\frac{1}{2}$, and $x$, we are asked to find the outputs if the functions 'square' and 'subtract $4$' act in succession. Let's follow this pattern below

$\text{II}\rightarrow[\text{square}]\rightarrow\text{OP 1}\rightarrow[-4]\rightarrow\text{FO}$

where $\text{II}$ is the initial input, $\text{OP 1}$ is the output $1$ is the result of the first function and will be the next input for the second function to get the final output $\text{FO}$.
