The domain for every parabola

• All real numbers

• Positive integers

• Negative integers

• Depends on the parabola

Answer explanation

The range of the parabola is all real numbers greater than or equal to -1, so the correct answer is y ≥ -1.

What is the domain and range of the following function:
y = 3x² -6x +5
