What is the solution set of the quadratic inequality f(x) greater than or equal to 0

stellarik [79]

ANSWER

{ $x | x \in \: R$ }

EXPLANATION

From the graph, the given quadratic inequality is

${(x + 3)}^{2} \geqslant 0$

We can see that the corresponding quadratic function is a perfect square.

Since the graph opens upwards and it is always above the x-axis, any real number you plug into the inequality, the result is greater than or equal to zero.

Hence the solution set is

{ $x | x \in \: R$ }

The correct answer is A
