O GRAPHS AND FUNCTIONS Combining functions: Advanced Suppose that the functions f and g are defined as follows. f (x) = 2x-5 g (x) = -5x+3 Find f. g and f-g. Then, give their domains using interval notation. ( f .E) (x) = 1 VO (0,0) [p.0] Domain of fog :] DVD (0.0] [0,0) OO (f - 8) (x) = 1 X 5 Domain of f - g : ]Given that, fly = 12x-5. My = -5x+3 ( f. g) () : This is the the multiplication of for and go . = (1/2X -5 ) x ( - 521+ 3 ) we need to make sure that the expression / 2x-5 is non - negative because the square root of a negative numbor is undefined so : 221 - 570 2x1 7/ 5 So, the domain of (figtry is [ 5 , 0) in interval notation
