Will it also be correct if I find the value of x by solving the inequality (x+2)^2 >= 0?
Yep the ans is correct thx!
I dont think you can do that because if you use inequality it means that you are finding for x-intercepts. but they are asking u to find the minimum value also means the minimum point of the graph
this method is using differentiation but for the topic you are learning now, the solution I added.
I see thank you
