Step-by-step explanation:
We have,
[tex]y=7x^2-3[/tex]
It is required to find the value of the discriminant. It is given by :
[tex]D=b^2-4ac[/tex]
Here, a = 7 b = 0 and c = -3
So,
[tex]D=(0)^2-4\times 7\times (-3)\\\\D=84[/tex]
The discriminant is positive here, it means that it has two distinct real number solutions.
