Determine the domain and range of the function

• Domain: All real numbers, Range: All real numbers

• Domain: x ≥ -4, Range: All real numbers

• Domain: All real numbers, Range: y ≥ -4

• Domain: -1 ≤ x ≤ 5, Range: y ≥ -4

Which quadratic in standard form is shown in the graph? (Hint: factored form reveals the x-intercepts)

• y = x² + 4x + 3

• y = x² - 4x + 3

• y = x² - 3x - 4

• y = x² +3x - 4
