Question

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

Answer 1

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

Step-by-step 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
