Please help me out! determine the domain on this graph

Mathematics
1 answer:
Bezzdna [24]3 years ago
3 0

Answer:

Domain: 6 </= x < 11

Step-by-step explanation:

Domain refers to the set of possible input values, therefore the domain of a graph consists of all the input values shown on the x-axis.

Remember (this is very important!) :

Closed circles means including that number whereas open circles means not including that number

Domain: 6 </= x < 11

Note: </= means "less than or equal to"

The graph of x^3 +y^3=4 is symmetric with respect to which of the following
vladimir2022 [97]

Answer:


Step-by-step explanation:

Without any choices, I would say it is symmetric around no common value. That is a guess. (left graph)

y^3 = x^3 is a straight line going through 0,0 and symmetric about the origin. That too is just a guess. (right graph)

What two positive real numbers whose product is 21 have the smallest possible​ sum?
GalinKa [24]

Answer:

x=\sqrt{21}

y=\sqrt{21}

Step-by-step explanation:

Let x  and y are the two positive real numbers

product of two numbers is 21

x y=21

y=\frac{21}{x}

The sum of the two numbers is f(x) =x+y

Replace y with 21/x

f(x) =x+\frac{21}{x}

we need to find smallest possible sum , so we take derivative using power rule

f'(x)= 1-\frac{21}{x^2}

when sum is minimum then the derivative is equal to 0

0= 1-\frac{21}{x^2}

0=\frac{x^2-21}{x^2}

multiply both sides by x^2

x^2-21=0

x^2=21

Take square root on both sides

x=\sqrt{21}

y=\frac{21}{x}

y=\frac{21}{\sqrt{21}}

y=\sqrt{21}
