Which оf the fоllоwing best describes the grаph's horizontаl аsymptote? The x-axis spans from negative 5 to just above 10, and the y-axis spans from below zero to above 40. The x-axis has a scale of 5 in increments of 1, while the y-axis has a scale of 20 in increments of 5. The blue convex curve begins in the bottom-right side of the first quadrant, just above the horizontal line y = 5. Initially, it remains flat as it moves left toward the origin and after passing the x value of 5, it rises towards the second quadrant. The curve crosses the y-axis at a point slightly below (0, 15) and continues to rise rapidly. It passes through the coordinates (negative 2, 40) and extends till out of view.
