Question

How to find the domain and range of y = log2(360-10x^2) ?

Answer 1

logrithm of negative numbers doesnot exists. now can you guess the domain???

Answer 2

x doesn't equal 6 or -6? Or would I say x must be greater than 6 or -6?

Answer 3

x can be from -6 to 6 but cannot less than -6 and cannot be greater than 6

Answer 4

So is this right: domain is { x| x ≠ 6, -6 }
