F ( x ) = 2 x + 3
g ( x ) = x²
Part 1 : f ( g ( x )) = f ( x² ) = 2 x² + 3
Part 2 : g ( f ( x ) ) = g ( 2 x + 3 ) = ( 2 x + 3 )² = 4 x² + 12 x + 9
Part 3:
Both parts represent the composition of functions. In the first part we are plugging function x² into f ( x ) and in the second part we are plugging
2 x + 3 into g ( x ).
Answer:
x = 1.8
Step-by-step explanation:
5x - - 5x makes 5x+5x which is equal to 10x
10x+21= 39
-21 -21
10x= 18
10x/10 = 18/10
x = 1.8
Alright, so you can try to study hard and gain a passing grade (A+) for the other two quarters.
(b^5)^2
b^10
you multiply the exponents. hope this helps, God bless!
2x-4(x+1)=-13
1) we solve this equation:
2x-4(x+1)=-12
2x-4x-4=-12
-2x=-12+4
-2x=-8
x=-8/-2
x=4
2) we evalute x²-1
x²-1=4²-1=16-1=15
Answer: 15
