Answer

**Asymptotes:** - Vertical: \( x = 1 \) - Horizontal: \( y = -2 \) **Intercepts:** - x-intercept: \( (2, 0) \) - y-intercept: \( (0, -4) \) **Line of Symmetry for \( m < 0 \):** - \( y = -2 \) **Values of \( x \) where \( f(x) \leq -4 \):** - \( 0 \leq x < 1 \)

Solution

It seems that I am unable to generate a plot at this moment. However, I can guide you on how to sketch the graph of \( f(x) \) based on the information we have gathered. ### Instructions to Sketch the Graph of \( f(x) \) 1. **Draw the Axes**: Start by drawing the x-axis and y-axis. 2. **Plot the Asymptotes**: - Draw a dashed vertical line at \( x = 1 \) (vertical asymptote). - Draw a dashed horizontal line at \( y = -2 \) (horizontal asymptote). 3. **Plot the Intercepts**: - Mark the x-intercept at \( (2, 0) \). - Mark the y-intercept at \( (0, -4) \). 4. **Behavior of the Function**: - As \( x \) approaches \( 1 \) from the left, \( f(x) \) will approach \( -\infty \). - As \( x \) approaches \( 1 \) from the right, \( f(x) \) will approach \( +\infty \). - As \( x \) approaches \( -\infty \), \( f(x) \) approaches \( -2 \). - As \( x \) approaches \( +\infty \), \( f(x) \) also approaches \( -2 \). 5. **Sketch the Curve**: - Draw the curve approaching the vertical asymptote from below as it approaches \( x = 1 \) from the left. - Draw the curve approaching the vertical asymptote from above as it approaches \( x = 1 \) from the right. - Ensure the curve approaches the horizontal asymptote \( y = -2 \) as \( x \) goes to both \( -\infty \) and \( +\infty \). 6. **Label Everything**: Clearly label the asymptotes, intercepts, and any important points on the graph. This will give you a complete sketch of the function \( f(x) \). If you have any further questions or need additional assistance, feel free to ask!

Beyond the Answer

The function \( f(x) = \frac{2}{x-1} - 2 \) has vertical and horizontal asymptotes. The vertical asymptote occurs where the denominator equals zero: \( x - 1 = 0 \), giving \( x = 1 \). The horizontal asymptote can be determined by looking at the behavior as \( x \) approaches infinity. As \( x \) becomes very large, \( f(x) \) approaches \( -2 \). Therefore, the horizontal asymptote is \( y = -2 \). To find the equation of the line of symmetry for \( m < 0 \): A function can potentially have symmetry based on its structure. In this case, since the function is a rational one \( (m < 0) \), we can assess whether it reflects over any line. Typically for the functions involving rational expressions and transformations, we analyze them but \( f(x) \) does not exhibit simple symmetry in standard forms. To determine for which values of \( x \) the inequality \( f(x) \leq -4 \) holds, we set up the equation: \[ \frac{2}{x-1} - 2 \leq -4 \] This simplifies to: \[ \frac{2}{x-1} \leq -2 \] Multiplying through by \( x-1 \) (and flipping the inequality if \( x-1 < 0 \)): After solving, we find that \( f(x) \) will be less than or equal to -4 for values in the intervals based on the critical points.
