Create a piecewise function that represents the graph.

(1 point)

f(x)={x+1,2x−1, −3≤x<−1−1≤x≤1


f(x)={1,2x−1,−3<x≤−1−1<x<1


f(x)={1,2x, −3≤x<−1−1≤x≤1


f(x)={1,2x−1,−3≤x<−1−1≤x≤1

Answer 1

f(x) = { 1, for −3 ≤ x < −1
2x − 1, for −1 ≤ x ≤ 1

Reason: the left segment is the constant y = 1 on [−3, −1), and the middle segment is the line y = 2x − 1 on [−1, 1].
