Question

which one of the following options is represented by the function given by f(x) = 3x2 -x-15
A Straight Line
B Circle
C Parabola
D Triangle

Answer 1

Dear Student,

$$\begin{gathered} \mathrm{We}\mathrm{know}\mathrm{that}\mathrm{general}\mathrm{equation}\mathrm{of}\mathrm{the}\mathrm{parabola}\mathrm{is}, \\ \mathrm{y}={\mathrm{ax}}^2+\mathrm{bx}+\mathrm{c} \end{gathered}$$

$\mathrm{Now},\mathrm{y}=3{\mathrm{x}}^2-\mathrm{x}-15\mathrm{is}\mathrm{the}\mathrm{equation}\mathrm{of}\mathrm{a}\mathrm{parabola}.$

Regards
