What are the features of the function f(x) = -2 log₂ (x+3) graphed below?

Isee the amount was $90.00 then reduced to $75.00 , what is the percent ?

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?
