Answer:

( f o f )(x) = f ( f (x))

   = f (2x + 3)

   = 2(           ) + 3    ... setting up to insert the input

   = 2(2x + 3) + 3

   = 4x + 6 + 3

   = 4x + 9Step-by-step

Answer:

x - 1/x, which is also f(x)

Step-by-step explanation:

hf(x) = x - 1/x + 1

hf(x) = x + 1 - 1/x

ghf(x) = x + 1 - 1/x - 1 = x - 1/x = f(x)

If (x - 4) varies inversely as (y + 3) and x = 8 when y = 2, what is x when y = - 1?
denpristay [2]

Answer:

x=14

Step-by-step explanation:

If two values are inversely proportional, their product must be maintained. That way, if one value goes up, the other goes down by the same extent.

Therefore, if (x-4) and (y+3) vary inversely, their product will be the same for all values of x-4 and y+3.

Let x=8 and y=2 as given in the problem. Substitute values:

(8-4)(2+3)=(4)(5)=20

Hence, the maintained product is 20.

Thus, we have the following equation:

(x-4)(y+3)=20

Substitute y=-1 to find the value of x when y=-1:

(x-4)(-1+3)=20,\\(x-4)(2)=20,\\x-4=10,\\x=10+4=\boxed{14}
