Question

Which of the following could be an example of a function with a domain [a,) and a range [b.) where a > 0 and b>0? A. A.x) = f (x - b) + a B. f.V)= vita - b c. fx) = -a + b O D. Ax) =/rta-b

Answer 1

option A and D have domain and ranges of the entire real number set.

option B has a domain (-a, /infinity)

so the example function with a domain is option C which is:

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