Question

Estimate the roots of the equation by graphing. Round to the nearest tenth and write in set form, such as {-1.2,3.4}.

x2 - 6= 0

Answer 1

Fish

Answer 2

Please graph:\[y=x^2\]
Next, please graph \[y=x^2-6.\]
Note that the 2nd graph looks the same as the first, except that you move the whole graph downward 6 units.

Now estimate where the graph of \[y=x^2-6\]
intercepts the x-axis. Those two values are your approx. roots.

The more careful you are in graphing this function, the more accurate your root estimations will be.
