Determine the direction that this parabola opens y=4x^2+8x+2

For this case we have a quadratic equation of the form:
 
 What we must keep in mind to know which direction opens the parabola, is the value of a.
 We have two options:
 If a <0 the parabola opens down
 If a> 0 the parabola opens up
 We have the following equation:
 
 We observed that:
 
 Therefore, the parable opens up.
 
 the direction that this parabola opens is:
 Upwards
