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.

write the formula of gravitational force between two bodies of mass 'x'and 'y' kept at a distance 'r'

Rudik [331]

$\huge \orange{F =G.\frac{xy}{r^2}}$

Step-by-step explanation:

Masses of the bodies are x and y

Distance at which they are kept is r

When two bodies are of masses x and y are placed at a distance r then the gravitational force acting on them is given as:

$\huge \purple{F =G.\frac{xy}{r^2}}$
Where G is the gravitational constant.

Write an equation for the function whose graph is described.

Naddika [18.5K]

Answer:

f(x)=-|x|+19

Step-by-step explanation:

so shifted 19 units up means

abosolute value of x + 19

and reflected in the x axis means that you have to put the - before the abosolute value.

so -|x|+19

Which one would the equation be?

aleksley [76]

Answer:

a. $y = \frac{2}{5}x - 6$

Step-by-step explanation:

The slope-intercept form of equation of a line is given as $y = mx + b$ . Where,

m = slope

b = y-intercept.

Rewrite the equations, $2x - 5y = 12$ and $4y + 24 = 5x$ , in the slope-intercept form by making y the subject of the formula. Then, derive our new equation that has the same slope as the first equation, and the same y-intercept as the second equation.
