Answer:

f(x) = (3x - 7)/5

f^-1(x) = (5y + 7)/3

The DOMAIN is the set of all possible numbers that you can put in for the independent variable and get an answer. If you had g(x) = 1/x, you could NOT put in 0 for x and get an answer because 1/0 is undefined. So the domain is all numbers but 0.

The RANGE is the set of numbers you will get for the dependent variable. If you had g(x) = 1/x, you could NOT get 0 for g(x), no matter what you put in for x. So the range is all numbers but 0.

In both your functions the domain and the range equal all possible numbers. Or all real numbers.

Step-by-step explanation:

Another way to write the answers is:

D = {x | x = R} and R = {f(x) | f(x) = R} where

D = domain, R = range, { } means set, | is such that.

Answer:

[-2, 4] or {-2, -1, 0, 1, 2, 3, 4}

Step-by-step explanation:

If you invert a func., it's range becomes the domain and it's domain becomes the range. So, if you want the domain of the inverted func, you'll need to find out the range of the original. That is, Domain of Inverse = Range of Original.

Range, pretty much, means the extremities bounds the y-values.

Here, for the original func., the y-extremities are -2 and +4, thus the range is [-2, 4] and hence the domain of the inverted func will be [-2, 4].

andriy [413]

It would be A because with volume you would have your 12 to the 3rd power then multiply it by pie which is 3.14 then for sphere you would then multiply what ever you got after multiplying 12 to the 3rd power then by 3.14 to the 4/3

Alicia is writing the program for a video game. For one part of the game she uses the rule ( x , y) ----> ( x - 3, y + 4) to

anastassius [24]

The "rule" being described here is nothing more than the input/output of a mathematical function.

For every input 'x' value supplied, you only need to subtract three to it. For every input 'y' value, you only need to add four to it. 

Example: I'll use variable 'm' to represent this function. Variable 'p' will represent the current input point. 

m(p) = p[x - 3, y + 4] = p[-7 - 3, 0 + 4] = p[-10, 4]. 'p[]" is just the point.

1.What are the coordinates of the vertices of ABC? Use the coordinates to find the lengths of AC and AB .

Andrew [12]

Answer/Step-by-step explanation:

✔️Coordinates of vertices ABC:

A(2, 2)

B(6, 2)

C(2, -1)

✔️AC = |2 - (-1)| = 3 units

AB = |2 - 6| = 4 units

2. Distance formula => $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Distance between B(6, 2) and C(2, -1):

$BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Where,

$B(6, 2) = (x_1, y_1)$

$C(2, -1) = (x_2, y_2)$

$BC = \sqrt{(2 - 6)^2 + (-1 - 2)^2}$

$BC = \sqrt{(-4)^2 + (-3)^2}$

$BC = \sqrt{16 + 9} = \sqrt{25}$

$BC = 5 units$

Pretty please help this work is hard

Arlecino [84]

Answer:

Parentheses, exponents, multiplication and division, and addition and subtraction

Step-by-step explanation:

You can remember this order by using PEMDAS. PEMDAS stands for parentheses, exponents, multiplication, division, addition, and subtraction, in that order. First up should be parentheses, then exponents, then multiplication and division, and finally addition and subtraction.
