The domain of the function f(x)=
is all numbers greater than or up to 2.
Given Function f(x)=![\sqrt{x-2}](https://tex.z-dn.net/?f=%5Csqrt%7Bx-2%7D)
We have to search out the domain of the function f(x)=![\sqrt{x-2}](https://tex.z-dn.net/?f=%5Csqrt%7Bx-2%7D)
Domain is that the value of x which we put within the function to induce the various values and range is that the value which we get after putting the worth.
f(x)=![\sqrt{x-2}](https://tex.z-dn.net/?f=%5Csqrt%7Bx-2%7D)
put the function =0
squaring either side we get
x-2=0
x=2
So the domain of the function f(x)=
is [2,∞) because we are able to put all values greater than 2 within the function.
Hence the domain of the function is [2,∞).

Answer:
1 hour
Step-by-step explanation:
Lea's speed = 22km/hr
Trevon's speed = 43km/hr in a direction opposite Lea's
How long does Trevon needs to drive before they are 65km apart.
Note : both took at the same time and in opposite direction.
Recall : speed = distance / time
Distance = speed * time
Distance between them = 65km
Let Trevon's distance = D2 = 43 * t
Lea's distance = D1 = 22 * t
t is the same since they both left at the same time.
D2 + D1 = 65
43t + 22t = 65
65t = 65
t = 65/65
t = 1 hour
