Answer

The range of the function is

y ≥ 1

Or better put

1 ≤ y < ∞

Step-by-step explanation

The range of a function refers to the region of values where the function can exist. It refers to the values that the dependent variable [y or f(x)] can take on.

The function given is\

f(x) = |3x - 1| + 1

From this function, the absolute value sign ensures that the term |3x - 1| is always equal or greater than 0. So, the function f(x) can only take on values from 1 till infinity.

Since, we are now sure that the function can only take on values from y = 1 till indinity, we can represent this with inequality as

(The function) ≥ 1 (that is, 1 and above)

So, the range of the function is

y ≥ 1

Or better put

1 ≤ y < ∞

Hope this Helps!!!
