Answer

To graph the function \( f(x) \), plot the absolute value \( |x| \) for \( x < 1 \) and the line \( -x + 2 \) for \( x \geq 1 \). The graph consists of a V-shape up to \( x = 1 \) and a straight line starting at \( (1, 1) \) going downward.

Solution

It seems that I am unable to generate a graph directly. However, I can guide you through the process of graphing the piecewise function step by step. The function is defined as follows: \[ f(x)=\left\{ \begin{array}{ll} |x| & \text{for } x<1 \\ -x+2 & \text{for } x \geq 1 \end{array} \right. \] ### Step 1: Graph the first piece \( f(x) = |x| \) for \( x < 1 \) 1. **Identify the function**: The absolute value function \( |x| \) is a V-shaped graph that opens upwards. 2. **Domain**: This part of the function is valid for \( x < 1 \). 3. **Key points**: - At \( x = 0 \), \( f(0) = |0| = 0 \). - As \( x \) approaches 1 from the left, \( f(1) = |1| = 1 \) (but this point is not included since it is for \( x < 1 \)). 4. **Plot the line**: Draw the line segment from \( (-\infty, 0) \) to \( (0, 0) \) and from \( (0, 0) \) to just before \( (1, 1) \). ### Step 2: Graph the second piece \( f(x) = -x + 2 \) for \( x \geq 1 \) 1. **Identify the function**: This is a linear function with a negative slope. 2. **Domain**: This part of the function is valid for \( x \geq 1 \). 3. **Key points**: - At \( x = 1 \), \( f(1) = -1 + 2 = 1 \) (this point is included). - At \( x = 2 \), \( f(2) = -2 + 2 = 0 \). 4. **Plot the line**: Draw the line starting from \( (1, 1) \) and continuing downwards to the right. ### Step 3: Combine the two pieces - The graph will consist of two parts: - The first part is a V-shape from the left up to but not including the point \( (1, 1) \). - The second part is a straight line starting from \( (1, 1) \) and going downwards. ### Final Notes - Make sure to indicate that the point at \( (1, 1) \) is included in the second piece but not in the first. - You can use graphing software or a graphing calculator to visualize this piecewise function accurately.

The Deep Dive

To graph the piecewise function \( f(x) \), we need to consider its two different rules based on the value of \( x \). 1. For \( x < 1 \): The function is \( f(x) = |x| \). This means for negative values of \( x \), the graph is a line whose value is the positive counterpart of \( x \). For example, at \( x = -1 \), \( f(-1) = 1 \), and at \( x = 0 \), \( f(0) = 0 \). 2. For \( x \geq 1 \): The function is \( f(x) = -x + 2 \). This is a straight line with a negative slope. At \( x = 1 \), \( f(1) = 1 \), and at \( x = 2 \), \( f(2) = 0 \). To graph: - Start by plotting the part \( f(x) = |x| \) for \( x < 1 \). This portion of the graph is the V-shape of the absolute value. It rises to the point \( (1, 1) \), but note that this point is open (not included since it's less than 1). - At \( x = 1 \), draw the point \( (1, 1) \) solid since it is included in the second part of the function. - For \( x \geq 1 \), graph the line \( f(x) = -x + 2 \) starting from \( (1, 1) \) and continuing downwards. This line will cross the x-axis when \( f(x) = 0 \), specifically at \( x = 2 \). The complete graph looks like a V rising on the left and a straight line falling on the right, meeting smoothly at the point \( (1, 1) \). By combining both parts, you create a unique piecewise graph reflecting both behaviors of the function.
