The domain is all real numbers. The range is {yly > 16).
The domain is xxl-5 The domain is {xl-5 5x53). The range is {yly s 16).

Answer 1

Answer:

Step-by-step explanation:

i can't see graph.

$f(x)=-x^2-2x+15=-(x^2+2x+1-1)+15=-(x-1)^2+1+15=-(x-1)^2+16\\domain=all~real~numbers.$

Range≤16

so A

Answer 2

The domain is all real numbers. The range is y less then or equal to 16.

Quadratic function

Quadratic function is a polynomial of degree 2. It is in the form:

f(x) = ax² + bx + c

where a, b, c are constants

The domain of a function is the set of input variables while the range of a function is the set of output variables.

From the image attached, The domain is all real numbers. The range is y less then or equal to 16.
