5x^2-y=12
y=5x^2-12
dy/dx=10x
d2y/dx2=10
Since acceleration is constant, which is true of all quadratics, and it is positive, there is an absolute minimum for y(x) when dy/dx=0. So it increases without bound on either side of the vertex, meaning that it opens upwards.

Answer:
The correct option is 1.
Step-by-step explanation:
In a quadratic equation:
If degree of x is 2 and leading coefficient is negative, then the parabola opens down.
If degree of x is 2 and leading coefficient is positive, then the parabola opens up.
If degree of y is 2 and leading coefficient is negative, then the parabola opens left.
If degree of y is 2 and leading coefficient is positive, then the parabola opens right.
The given function is
[tex]5x^2-y=12[/tex]
Here, the degree of x is 2 and the leading coefficient is positive, therefore this parabola opens up and the correct option is 1.
