Question

What is the range of the function `f(x)= -6(x+4)^2-12`?

Answer 1

See explanation.

Explanation:

The graph of the function is:

graph{-6(x+4)^2-12 [-12.66, 12.65, -15, 0.5]}

From the graph we can see that it takes all values smaller than or equal to `-12`, so the range of the function is:

`r=<-12;+oo)`
