Question

Determine the domain and range of the quadratic function f(x)=−6(x+1)2−9 .(1 point)Responsesdomain R ; range y≤9 domain the real numbers ; range y less-than-or-equal-to 9domain R ; range y≤−9 domain the real numbers ; range y less-than-or-equal-to negative 9domain R ; range y≥−9 domain the real numbers ; range y is greater than or equal to negative 9domain R ; range y≥9

Answer 1

Domain: all real numbers, (-∞, ∞).
Range: y ≤ −9 (maximum value −9 at x = −1).
