Answer:
(fcircle◦g)(x) : -30x- 35. domain: (-infinity, +infinity)
(gcircle◦f)(x) : -30x+ 50. domain: (-infinity, +infinity)
Step-by-step explanation:
The circle simply means to replace the x in the function with the other function. The domain is the x values. Since both of these equations are linear, it's negative infinity to infinity.
(fcircle◦g)(x): -10( 3x +5) +15
-30x -50 +15
-30x -35
(gcircle◦f)(x): 3(-10x +15) +5
-30x + 45 + 5
-30x +50
