Out of time and my mind
what are the domain and range of the real-valued function f(x)=−2√x+7?
select one:
a. the domain is x≥−7x, and the range is f(x)≥−2.
b. the domain is x≥7x, and the range is f(x)≥−2
c. the domain is x≥−7x, and the range is all real numbers.
d. the domain is x≥−7x, and the range is f(x)≥2.
