Answer:
domain is set of all real numbers
Range is [tex]y\leq 16[/tex]
Step-by-step explanation:
[tex]f(x)=-x^2-2x+15[/tex]
Domain is the set of x values for which the function is defined
In f(x), we have y values for all x values, So there is no restriction for x
Hence domain is set of all real numbers
Range is the set of all y values for which the function is defined
From the graph of the given function f(x), the maximum point that is vertex at (-1,16)
The range of the function is y<=16
Range is [tex]y\leq 16[/tex]
