evaluate the step - function defined by f(x)=x for the given value of x. f(1)=
Answer
Explanation:
Step1: Recall step - function definition
The step - function $f(x)=[[x]]$ is the greatest integer less than or equal to $x$.
Step2: Evaluate for $x = 1$
When $x = 1$, the greatest integer less than or equal to $1$ is $1$. So $[[1]]=1$.
Answer:
$1$
