What we do is to substitute to solve.

'(g(h(0))) 

g(x) = 2x
g(h(x)) = 2 (x^2 + 4)
(gh)(0) = 2 (0^2 + 4)  = 8

If this is supposed to be multiplication, this is the answer.
(g*h)(0)
2x(x^2 + 4) =
2x^3 + 8x =
2(0) + 8(0) = 0

If this is supposed to be something else and you forgot the operator between the g and h, let me know and I will redo it for you.

Matteo is adjusting a satellite because he finds it is not focusing the incoming radio waves perfectly. The shape of his satelli
natka813 [3]

Answer: (1.5, 0)

Step-by-step explanation:

Given : The shape of his satellite can be modeled by y^2=6x where x and y are modeled in inches.

Now,the given equation y^2=6x is a equation of parabola.

Here, coefficient of x is positive, hence the parabola opens rightwards.

On comparing this equation with standard equation x^2=4mx, we get

4m=6\\\Rightarrow\ m=\frac{6}{4}=1.5

In standard equation, coordinates of focus=(m,0)

Thus for given equation coordinates of focus=(1.5,0)

Create and describe a function related to your field (or intended field). Give a detailed explanation of the domain (input) and
Andru [333]

An example of a domain that can be illustrated from the information given will be D(x) = 32.

<h3>Domain and range</h3>

An example based on the information given is "A gas tank in John's car can hold 20 gallons of gas and the car gets 32 miles for every gallon".

John fills up the tank and then goes on a trip. In this case, the distance that will be travelled on one tank will be:

D(x) = 32x

In the above function, it should be noted that the number of gallons can be from 0 to 20. Since he gets 32 miles per gallon, the car can travel 640 miles.

In this case, the domain is the number of gallons that can be used. The number of miles will be the range.
