Find the domain of the function
Svetradugi [14.3K]

Answer:

<em>The domain of f is (-∞,4)</em>

Step-by-step explanation:

<u>Domain of a Function</u>

The domain of a function f is the set of all the values that the input variable can take so the function exists.

We are given the function

f(x)=\frac{1}{\sqrt{4-x} }

It's a rational function which denominator cannot be 0. In the denominator, there is a square root whose radicand cannot be negative, that is, 4-x must be positive or zero, but the previous restriction takes out 0 from the domain, thus:

4 - x > 0

Subtracting 4:

- x > -4

Multiplying by -1 and swapping the inequality sign:

x < 4

Thus the domain of f is (-∞,4)

NEED THE ANSWER ASAP PLEASE
Firdavs [7]

Answer:

AB = 5

Step-by-step explanation:

Since the triangle is isosceles then the legs are congruent, that is

BC = BA, substitute values

5x - 10 = 3x - 4 ( subtract 3x from both sides )

2x - 10 = - 4 ( add 10 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Thus

AB = 3x - 4 = 3(3) - 4 = 9 - 4 = 5

create a function and explain why it is a function using academic vocabulary (input ,output, mapping, vertical line test and fun
Tems11 [23]
An example would be using points
(0,0)(1,2)(7,14)(10,20)

it is a function because each input has only one input.

or

using the vertical line test none of the points are on the same line
