The correct Answer is:
To draw the graph of the function \( y = \frac{1}{|x|} \), we will analyze the function for different values of \( x \) and sketch the graph accordingly. Here are the steps involved: ### Step 1: Understand the Function The function \( y = \frac{1}{|x|} \) is defined for all \( x \) except \( x = 0 \) because division by zero is undefined. The absolute value \( |x| \) ensures that the output \( y \) is always positive for \( x \neq 0 \). ### Step 2: Analyze for \( x > 0 \) For \( x > 0 \), the modulus function does not change the value of \( x \): \[ y = \frac{1}{|x|} = \frac{1}{x} \] As \( x \) approaches 0 from the right, \( y \) approaches infinity. As \( x \) increases, \( y \) decreases towards 0. ### Step 3: Analyze for \( x < 0 \) For \( x < 0 \), the modulus function changes the sign of \( x \): \[ y = \frac{1}{|x|} = \frac{1}{-x} \] As \( x \) approaches 0 from the left, \( y \) also approaches infinity. As \( x \) becomes more negative, \( y \) decreases towards 0. ### Step 4: Identify Key Points - When \( x \) is very close to 0 (from either side), \( y \) is very large (approaching infinity). - When \( x = 1 \), \( y = 1 \). - When \( x = -1 \), \( y = 1 \). - As \( x \) approaches positive or negative infinity, \( y \) approaches 0. ### Step 5: Sketch the Graph 1. Draw the coordinate axes (x-axis and y-axis). 2. For \( x > 0 \), plot the curve of \( y = \frac{1}{x} \) which approaches the y-axis as \( x \) approaches 0 and approaches the x-axis as \( x \) increases. 3. For \( x < 0 \), plot the curve of \( y = \frac{1}{-x} \) which also approaches the y-axis as \( x \) approaches 0 and approaches the x-axis as \( x \) becomes more negative. 4. Mark the asymptotes at \( x = 0 \) (vertical asymptote) and \( y = 0 \) (horizontal asymptote). ### Final Graph The final graph will consist of two branches: - One in the first quadrant for \( x > 0 \) (decreasing from infinity to 0). - One in the second quadrant for \( x < 0 \) (decreasing from infinity to 0).
