Question

write the conditions in which graph of p(x) = ax²+bx+c is upward parabola and downward parabola

Answer 1

$$\begin{gathered} \mathrm{For}\mathrm{the}\mathrm{expression}{\mathrm{ax}}^2+\mathrm{bx}+\mathrm{c}=0 \\ \mathrm{If}\mathrm{a}>0\mathrm{then}\mathrm{parabola}\mathrm{will}\mathrm{be}\mathrm{upward}. \\ \mathrm{and}\mathrm{if}\mathrm{a}<0\mathrm{then}\mathrm{parabola}\mathrm{will}\mathrm{be}\mathrm{downward}. \end{gathered}$$
