Can you please tell me how to solve this question!!

A graph of quadratic function y = f(x) is shown below. (look at the picture)
What is the solution set of the quadratic inequality f(x) ≥ 0?

Can you please tell me how to solve this question A graph of quadratic function y fx is shown below look at the picture What is the solution set of the quadrati class=

Respuesta :

check the picture below.

keep in mind that the yellow shaded area is the "true" region, namely where f(x) ⩾ 0, and the values "x" takes on are pretty much all real values.

Answer:

The solution set of the inequality f(x) ≥ 0 is:

           All the real values i.e. whole of the real line or x∈R

Step-by-step explanation:

By looking at the graph of the function f(x) we observe that the function is a parabolic function such that it takes all the positive values since the graph lie above the x-axis.

This means that the value of the function is: f(x) ≥ 0 for all x

And also we know that a quadratic function is defined all over the real axis.

Hence, the solution  to the inequality:

                     Whole real line i.e. x ∈ R
