Use the image to answer the question.

Two lines, a solid line and a dotted line, are drawn on a coordinate plane. Both the x-axis and y-axis range from negative 4 to 4 in 1-unit increments.

Create a piecewise function that represents the graph.

To construct the piecewise function representing the graph with the given constraints, we will analyze the function in regions defined by the x-values.

Assuming that the solid line corresponds to the function \( f(x) = 2x - 1 \) and is only valid for \( -1 < x < 1\), and that a constant function \( f(x) = 1 \) is valid for \( -3 \leq x < -1\), we can represent this using a piecewise function as follows:

Given the information provided together with common piecewise structures:

  • It seems that for \( -3 \leq x < -1 \), the function equals 1.
  • For \( -1 \leq x < 1 \), the function equals \( 2x - 1 \).

Thus, the piecewise function can be represented as:

\[ f(x) = \begin{cases} 1 & \text{if } -3 \leq x < -1 \ 2x - 1 & \text{if } -1 \leq x < 1 \end{cases} \]

Now, let's match this with the provided options. The correct form looks like:

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

Based on the responses you provided, the last one, which follows the structure I defined, seems to denote:

f left parenthesis x right parenthesis equals left brace Start 2 by 2 Matrix 1st Row 1st Column 1 comma 2nd Column negative 3 less-than-or-equal-to x less than negative 1 2nd Row 1st Column 2 x minus 1 comma 2nd Column negative 1 less-than-or-equal-to x less-than-or-equal-to 1 End Matrix.

Thus, the correct answer is: f(x)={1,2x−1,−3≤x<−1,−1≤x<1.
