To analyze the function \( f(x) = \frac{9x}{1 - x^2} \), we first need to determine its domain. The function is undefined when the denominator equals zero, so we set \( 1 - x^2 = 0 \). This simplifies to \( x^2 = 1 \), leading to \( x = 1 \) and \( x = -1 \). Therefore, the domain is all real \( x \) except \( x = 1 \) and \( x = -1 \). A. The domain of \( f(x) \) is all real \( x \), except \( x=1, -1 \). Now, let's dive into the graph! The function \( f(x) \) exhibits vertical asymptotes at \( x = 1 \) and \( x = -1 \) due to the undefined values. As \( x \) approaches these points, \( f(x) \) tends to ±∞. The horizontal asymptote can be determined by examining the degrees of the numerator and denominator, leading us to see that as \( x \) tends to ±∞, \( f(x) \) approaches 0. Therefore, the graph will have two branches, one in the first quadrant and another in the third quadrant, symmetrically located about the origin.
