Answer:

\boxed{\boxed{f\bigg(g(2)\bigg)=0}}

Step-by-step explanation:

f(x)=x^2-2,\ g(x)=\sqrt{x}\\\\Domain:\\D_f:x\in\mathbb{R}\\\\D_g:x\geq0\\\\f(g(x))=\left(\sqrt{x}\right)^2-2=x-2

Used:\\\\(\sqrt{a})^2=a

f(g(2)):\\\text{Put x = 2 to the equation of the function:}\\\\f(g(2))=2-2=0

Answer:

The value of f(g(2)) is 0

Step-by-step explanation:

Given:

f(x) = x^2-2 and g(x) = \sqrt{x}

we have to find the f(g(2)).

first find g(2)

Put x =2 in g(x) we have;

g(2) = \sqrt{2}

Now;

f(g(2))=f(\sqrt{2})=(\sqrt{2})^2-2 = 2-2 = 0

Therefore, the value of f(g(2)) is 0

Jonesville and smithville each have a population of size 2600 at time t = ​0, where t is measured in years. Suppose jonesville​'
ehidna [41]

Answer: B. Jonesville is growing linearly and Smithville is growing exponentially.

Step-by-step explanation:

Linear growth :

  • Population grow by a constant amount after each time period.
  • The rate of change of dependent variable with respect to independent variable is a constant.
  • It is represented by line on graph.
  • Equation for linear growth : y=mx+c , c = initial value and m is the rate of change of y with respect to x.

Exponential growth :

  • Population grow by a constant ratio .
  • It is represented by a curve on graph.
  • Equation for exponential growth : y=a(1+r)^x , a = initial value and r is  rate of growth ( in decimal ) and x is time period.

Given : Jonesville​'s population grows by 170 people per year.

i.e .Population grow by a constant amount per year.

⇒ Jonesville is growing linearly.

The population of smithville grows by 7​% per year.

i.e. Population grow by a constant ratio.

⇒Smithville is growing exponentially.

Hence, the true statement is "B. Jonesville is growing linearly and Smithville is growing exponentially."
