Question

How do you solve `x^2+5=0` by graphing?

Answer 1

No solution

Explanation:

This question is basically asking do the lines `y=x^2+5` and `y=0` intersect at any points

graph{x^2+5 [-18.02, 18.02, -9.01, 9.01]}
Above is the graph `y=x^2=5`. Now, hopefully you see that the graph does not intersect with `y=0` or the x-axis at any point. Therefore, the answer is no solution
