The exponent $\displaystyle{{x}}^{{2}}\usepackage{cmbright}\Huge\$ indicates that the curve will be in the shape of a parabola, and the positive coefficient 4 ensures that it opens upward. The intercept form is $\displaystyle{y}={4}{{\left({x}+{1}\right)}}^{{2}}\usepackage{cmbright}\Huge\$ , which means there is one root at $\displaystyle{\left(-{1},{0}\right)}\usepackage{cmbright}\Huge\$ .
