The composite function
works like this:
- Take a number
as input - Evaluate h(x) = 3x. Let's call this output z.
- Evaluate g(x) = 1/(z+2)
So, if we substitute back z = 3x, the final output is 1/(3x+2). We know that the denominator of a fraction can't be zero, so we must impose

Answer:
x = sqrt(7) or x = -sqrt(7) thus of the choices you have A:
Step-by-step explanation:
Solve for x:
x^2 = 7
Take the square root of both sides:
Answer: x = sqrt(7) or x = -sqrt(7)
Answer:
28/6 yeah thats right wasp
Amy(A): D + 12
Doug(D):D
Ginger(G):2D
SumOfAll(S)=208 : Total points / sum of all three friends
(D+12)+D+2D=208
D+12+3D=208 - transpose 12 to the right side
4D=208-12
4D = 196 - divide both sides by 4
D=49
Therefore, Doug scored 49
