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

Hello.

The solutions to quadratic inequalities are their roots, zeros, and x-intercepts.

The graph of this equation is shown below.

Therefore, the solution set is the set of all real numbers, which is the first choice.

Option A:{x/ x∈R}

Step-by-step explanation:

The given quadratic inequality is f(x)≤0.

Replacing f(x) by y we have: y≤0.

y=0 on the x axis .Any quadratic equation represents a parabola.

The  solution to the inequality will either be "all x" or "no x" it depends on  the side of the axis the parabola will lie.

As the quadratic inequality is f(x)≤0 so the  graph will be below the x axis and the solution set will be the set of real numbers.

Solution of the quadratic inequality is Option A:{x/ x∈R}.

man its nopq i just guessed and got it right so uhh
