What problem or problems could we potentially run into if we use graphs to find the exact roots
Nookie1986 [14]

The possible problems  of using graphs to find roots are:

  • Having complex roots.
  • Having irrational roots.

<h3>How to find the roots of a quadratic function with a graph?</h3>

First, the roots of a quadratic function are the values of x such that:

a*x^2 + b*x + c = 0

To find the roots using a graph, we need to see at which values of x does the graph of the parabola intercepts the horizontal axis.

<h3>What are the possible problems with this method?</h3>

There are two, the first one is having irrational roots, in that case, an analytical or numerical approach will give us a better estimation of the roots. Finding irrational values by looking at the intercepts of the graph can be really hard, so in these cases using the graph to find the roots is not the best option.

The other problem is if we <u>don't have real roots</u>, this means that the graph never does intercept the horizontal axis. In these cases, we have complex roots, that only can be obtained if we solve the problem analytically.
