Interactive popup. Assistance may be required.

Check Answer

When x < -3 or x ≥ 0, numerator x denominator x + 3 is greater than or equal to 0 x x + 3 ≥ 0.

Problem 2

Solve numerator x + 2 denominator x – 1 is less than or equal to 0 x + 2 x – 1 ≤ 0 using the table feature on your graphing calculator.

Interactive popup. Assistance may be required.

Check Answer

When -2 ≤ x < 1, then numerator x + 2 denominator x – 1 is less than or equal to 0 x + 2 x – 1 ≤ 0
