Quadratic Inequalities Interval Notation

Look at the graph. Write the inequality in interval notation.

What inequality is represented on the number line?

Which of these is part of the solution set of x² - 3x + 4 > 0?

Which of the following is not a solution to -x² + 3x + 10 < 0 ?

Which of the following is the interval notation of x² - x - 12 < 0?

2x² + 5x ≥ 12 , then find the interval notation of the inequality.

Which of the following is the interval notation of x² - x - 12 < 0?

It is an expression in the form $$ax^2+bx+c>0,\$$  or any from the symbols  $$<,\le,\ge,\ or\ne,$$ where the solution of x hold inequality.

Solve:

3x - x² > 0 , then find the interval notation of the inequality.

It is similar to quadratic equation, except instead of an equal sign there’s an inequality sign.
