The solid line starts with a closed circle at left parenthesis negative 3 comma 1 right parenthesis and ends with an open circle at left parenthesis negative 1 comma 1 right parenthesis. The dotted line starts
with a closed circle at left parenthesis 1 comma 1 right parenthesis and ends with a closed circle at left parenthesis negative 1 comma negative 3 right parenthesis.

Create a piecewise function that represents the graph.

(1 point)

O f(x)=1, -3<x <- 1
12x-1,-1<x<1

(1,-3<x <- 1
O f(x) =

fx+1, -3<x <- 1
O f(x) =

(1,
12x-1,-1<x<1

Answer 1

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

(First piece is the solid horizontal segment from (-3,1) to the open point at (-1,1); second piece is the line joining (-1,-3) to (1,1).)
