What is the domain of f(x)=(1/2)^x

Need asap. solve for the following inequality

The point (-7, -24) is on the terminal ray of angle 0 which is in standard position. a student found the six trigonometric values for angle e. the student's answers are shown. which value(s) are incorrect? sin(8) cos(8) 24 tan(0) sin(0)=25 cos(0) -- tan(ⓡ) - - 24 csc(o)=2 sec(0) --25 cot(6) - za csc(o) sec(0) cot(0) done

If f(x) = 5х – 2 and g(x) = 2х + 1, find (f – g)(x).
