Question

Find the range of function f(x)=|x-1| +3
​

Answer 1

Answer:

[3,∞)

Step-by-step explanation:

The range of a function is the collection of all the possible values that a function can give.

Here because of the modulus, the lowest value of |x-1| can be 0 (when x=1)

and the highest is ∞, naturally.

When |x-1| = 0, the value of the function is 3. so 3 is the lowest value and ∞ is the highest one, thus the set {3,∞) is the range.
