What are a domain and range?
Nikolay [14]

Answer:

The domain and range of function is the set of all possible inputs and outputs of a function respectively.

The domain and range of a function y = f (x) is given as domain= {x ,x∈R }, range= {f (x), x∈Domain}.

The domain and range of any function can be found algebraically or graphically.

The functions f(x) = −(x − 1)2 5 and g(x) = (x 2)2 − 3 have been rewritten using the completing-the-square method. apply your kn
ale4655 [162]

The vertex of the function f(x) exists (1, 5), the vertex of the function g(x) exists (-2, -3), and the vertex of the function f(x) exists maximum and the vertex of the function g(x) exists minimum.

<h3>How to determine the vertex for each function is a minimum or a maximum? </h3>

Given:

$\mathrm{f}(\mathrm{x})=-(\mathrm{x}-1)^{2}+5$ and

$\mathrm{g}(\mathrm{x})=(\mathrm{x}-2)^{2}-3$

The generalized equation of a parabola in the vertex form exists

$y=a(x-h)^{2}+k

Vertex of the function f(x) exists (1, 5).

Vertex of the function g(x) exists (-2, -3).

Now, if (a > 0) then the vertex of the function exists minimum, and if (a < 0) then the vertex of the function exists maximum.

The vertex of the function f(x) exists at a maximum and the vertex of the function g(x) exists at a minimum.

To learn more about the vertex of the function refer to:

What is the volume of the composite figure? (Round to the nearest hundredth. Use 3.14 for Pi.)
Natasha2012 [34]

The volume of composite figure is 385.17 cubic centimeters, if a half sphere and cone have a radius of 4 centimeters and height of 15 centimeters.

Step-by-step explanation:

The given is,

              Composite figure is combination of a  half sphere and cone

              Both have a radius of 4 centimeters

              The cone has a height of 15 centimeters

Step:1

   Volume of composite figure = Volume of half sphere + Volume of cone  

Step:2

     Formula for volume of semi sphere,

                                    Volume of half sphere, V_{Half sphere} = \frac{2}{3}  \pi  r^{3}

     Where, r - Radius of Half sphere,

     From given, r = 4 centimeters

                                    V_{Half sphere} = \frac{2}{3}  \pi  4^{3}

                                                       = (0.6667) (3.14)  (64)        (∵ \pi = 3.14 )

                                      V_{Half sphere} = 133.9733 cubic centimeters

     Formula for volume of cone,

                      Volume of cone, V_{cone} = \frac{1}{3} \pi r^{2} h

     where, r - Radius of cone

                h - Height of cone

     From given,

                 r = 4 centimeters

                h = 15 centimeters

     Volume of cone,

                                                V_{cone} = \frac{1}{3} \pi 4^{2}(15)    

                                                         = (0.333333) (3.14)(16)(15)       (∵ \pi = 3.14 )

                                                 V_{cone} = 251.1997 cubic centimeters

Step:3

        Volume of composite figure =  133.9733 + 251.1997

       Volume of composite figure  = 385.17 cubic centimeters

Result:

         The volume of composite figure is 385.17 cubic centimeters, if a half sphere and cone have a radius of 4 centimeters and height of 15 centimeters.
