The limits of a quadratic function Here is the equation of the quadratic: $\dfrac{1}{10}x^2+3x+5$
Here is the graph visually:

I was wondering what value $y$ heads towards if the $x$ value is heading towards negative infinity. 
My answer: infinity 
For this, I looked at the negative $x$ values, then looked at their outputs. Their outputs seemed to be heading towards infinity. Is this the correct way of approaching this problem?

From the graph, you can realize that as x goes toward negative infinity f(x) heading toward positive infinity. This limit is unbound or undefined.
