A data analyst fits a non-linear regression model of the form y=β0+β1x2+ϵy = \beta_0 + \beta_1 x^2 + \epsilon to a dataset. After fitting the model, a residual plot is generated, showing the residuals (ei=yiy^ie_i = y_i - \hat{y}_i) against the independent variable xix_i. If this model is a good fit for the data, which of the following patterns should ideally be observed in the residual plot?
