Which of the following represents the equation of a quadratic curve?y = 3x + 7y = 8 - 3x + 7x2y = 7(3)xy = 8 x 6

Sagot :

An equation will be a quadratic curve when the expression has the following definition

[tex]y=ax^2+bx+c[/tex]

We can have b and c equal to 0, but never a, therefore we have few variations like

[tex]\begin{gathered} y=ax^2+bx \\ y=ax^2+c \\ y=ax^2 \end{gathered}[/tex]

All they are quadratics. Looking at the options we can see that the only function that has that definition is

[tex]y=8-3x+7x^2[/tex]

Therefore the correct answer is

[tex]y=8-3x+7x^{2}[/tex]
