What are the DOMAIN and RANGE of the function shown?

• Domain: -1 ≤ x ≤ 5

• Range: f(x) ≥ -3

• Domain: All real numbers

• Domain: x ≥ 2

• Range: f(x) ≥ -2

• The DOMAIN of function h is all real numbers.
• The DOMAIN of function h is all real numbers less than -36.

• The RANGE of function h is all real numbers.

• The RANGE of function h is all real numbers less than -36.

What is the range for this situation?

• All real numbers less than or equal to 100

• All real numbers less than or equal to 2.5

• All real numbers greater than or equal to 0 and less than or equal to 100

• All real numbers greater than or equal to 0 and less than or equal to 2.5

Which statements appear to be true? Select TWO correct answers.

• The vertex is at (-4, -1)

• The minimum value is at -4

• The minimum value is at -3

• The zeros are at (-3, 0) and (1, 0)

• The function has no zeros

• g(x) = 42x² - 83x + 40

• g(x) = 42x² - 13x - 40

• g(x) = 42x² + 83x + 40

• g(x) = 42x² + 13x - 40

• y = -x² + 6x - 13

• y = -x² - 6x - 13

• y = x² - 6x + 13

• y = x² + 6x + 13

• 2, 6

• 2, -6

• -2, 78

• 2, -78

• (-3, 8)

• (8, -3)

• (3, 8)

• (-3, -8)
