## anonymous one year ago Which of the following could be an example of a function with a range (-infinity, a] and a domain [b , infinity) where a > 0 and b > 0? A. f(x) = -sqrt(x-b) + a B. f(x) = cubert(x+b) - a C. f(x) = -cubert(x+a) - b D. f(x) = sqrt(x-a) + b *** I will make equations more readable***

$A. f(x) = -\sqrt{x-b} + a$

$B. f(x) = \sqrt[3]{x+b} - a$

$C. f(x) = -\sqrt[3]{x+a} - b$

$D. f(x) = \sqrt{x-a} + b$

Using what I know, I think the answer would be letter A because that is the only equations (I think) that has a negative range and a positive domain. Please help!
