Which оf the fоllоwing is а verticаl аsymptote of ( y = frac{x^2}{x^2 - 4x} )? The x-axis spans from below negative 5 to above 10, and the y-axis spans from below negative 40 to above 20. The x-axis has a scale of 5 in increments of 1, and the y-axis has a scale of 20 in increments of 5. The convex curve spans the first quadrant, passing through the points (4.5, 10) and (7, 2.5). It starts from positive infinity near x = 4 and decreasing toward the horizontal asymptote near y = 0. The concave curve spans the second and fourth quadrants, passing through the points (negative 1, 0) and (3.5, 7.5). The curve starts from negative infinity near the vertical line x = 4, passes through the origin (0, 0) and levels out horizontally near the negative x-axis.
