2.1. A curve C is defined by the parametric equations x = :2, y = t3 t a. Determine the valueis] of t for which the curve is increasing or decreasing. Once determined. use a graphing utility like Desmos and plug in a range of t values into the program that are consistent with your solution {see it visually traced Out on the Curve}. Summarize your result tracing out the portions of the curve below with appropriate t-domains. b. Determine the valueis} of t for which the Curve is concave up or concave down. Once determined, use a graphing utility like Desmos and plug in a range of t values into the program that are consistent with your solution [see it visually traced out on the curve]. Summarize your result tracing out the portions of the curve below with appropriate t-domains
