Video Transcript

we want to evaluate the composition F G zero well, the G function is to X plus. Threes would be two times zero plus three two time 00 plus three is three, so it's really f of 31 we want to find in the F function is expert Plus four. So it's three squared plus four. Three squared is nine plus four is 13.
