Assuming

#### Explanation:

We wish to find the roots of the function

By root, we mean any value of

Multiply both sides by

Let this first root we found be

Yes. If the function has domain and range over the real numbers

We can verify this graphically, too:

graph{(y-1/4x^3+2)=0 [-7.9, 7.9, -3.31, 4.59]}
