Question

Determine the domain and range of the given function.

Answer 1

Answer:

The domain is all real numbers

The range is all real numbers greater than or equal to $-2$

Step-by-step explanation:

we know that

The function in the figure is a vertical parabola

The vertex of the function is the point $(0,-2)$

The parabola open upward------> the vertex is a minimum

The domain is the interval------> (-∞,∞)

The domain is all real numbers

The range is the interval------> [-2,∞)

$y\geq-2$

The range is all real numbers greater than or equal to $-2$

Answer 2

The domain is all real numbers the range is all real numbers greater than or equal to negative 2
