## Question:

What is the value of f(1)?

The function f (1) has the value between the second interval of [1,2]. The value of the function, is 1, as,

### What is step function?

Step function is represent in the steps of linear equation over the graph. Step function keeps the constant values at the difference places.

Given information-

The step function are graphed in the given problem.

Keep the values of variable x to find the value of at difference places.

The value of has to be find out.

The middle (third) interval [0,2], is closed at 0 but open at 2. Therefore when the value of x is between the 0 and 1.9999…, the value of function is 0.

Thus the function of the middle step is,

For the second interval, [1,2], function is closed at 1 but open at 2. Therefore when the value x is between the 1 and 1.999... , the value of function is -1,

Thus the function of the second step is,
