Please help . Select the correct answer. What is the domain of function.? P(x) = square root x-1 + 2
Answers
Answer:
B
Step-by-step explanation:
A square root can‘t be negative so
x -1 ≥ 0
x ≥ 1
We can say that the domain is
[1 ; +oo)
The function p(x)=[tex]\sqrt{x+1}+2[/tex]. The domain of the function is [1,∞) or {x|x≥1}.
Given that,
The function p(x)=[tex]\sqrt{x+1}+2[/tex]
We have to find the function domain.
What id domain of the function?The sets of all the x-coordinates and all the y-coordinates of ordered pairs, respectively, make up the domain and range of a relation.
The components of a function are its domain and range. Range, Domain, and Function. If a function f: A→ B exists that maps every element in A to an element in B, then A is the domain and B is the co-domain. The representation of an element 'a' under a relation R is given by 'b', where (a,b) R. The range of the function is the set of photos. In general, a function's domain and range are denoted as follows: Domain(f) = {x ∈ R} and range(f)={f(x) : x ∈ domain(f)}.
The domain of the function is [1,∞) or {x|x≥1}.
Therefore, The domain of the function is [1,∞) or {x|x≥1}.

50 POINTS. A ball is thrown into the air from a height of 4 feet at time t = 0. The function that models this situation is h(t)= -16t^2 + 64t + 4, where t is measured in seconds and h is the height in feet. What domain makes sense for this function
Answers
Answer:
The domain that makes sense for this function is all values greater than or equal to 0.
Step-by-step explanation:
A ball is thrown into the air from a height of 4 feet at time t = 0. It is modeled by the function:
[tex]h(t)=-16t^2+64t+4[/tex]
The domain of the function is time t. The range of the function is the ball's height in the air h.
Since time is our domain, we must restrict our domain to values equal to or greater than 0 since time cannot be negative.
Therefore, the domain that makes sense for this function is all values greater than or equal to 0.
In interval notation, this is:
[tex][0, \infty)[/tex]
And as an inequality:
[tex]t\geq 0[/tex]

Step-by-step explanation:
V=h*w*l V=pir^2*h
V=12*8*14 . V=pi*4^2*8
V=1344 . V=402.1
V1+V2=1344+402.1=1746.1
V=pi*r^2*h V=2/3*pi*r^3
