Answer:

x \le 3

x \ge 0

Step-by-step explanation:

The functions, missing from the question are:

f(x) = \sqrt{3 - x

f(x) = \sqrt{3 x

Required

Determine the domain

To get the domain, means we want to get the possible values of x.

(a)

f(x) = \sqrt{3 - x

Equate 3 - x to 0

3 - x = 0

Solve for x

-x = -3

x = 3

From the calculated value of x above;

When x exceeds 3; f(x) = undefined

So: the domain is:

x \le 3

(b)

f(x) = \sqrt{3x

Equate 3x to 0

3x = 0

Solve for x

x = 0

From the calculated value of x above;

When x falls below 0; f(x) = undefined

So: the domain is:

x \ge 0

Please help me with this question. what is the area?

The formula for that area would be A=1/2xbxh so you would do A=1/2x3.5x3 and that equals 5.25

Plz help me with this one..
Virty [35]

Answer:

The equations 3·x - 6·y = 9 and x - 2·y = 3 are the same

The possible solution are the points (infinite) on the line of the graph representing the equation 3·x - 6·y = 9 or x - 2·y = 3 which is the same line

Step-by-step explanation:

The given linear equations are;

3·x - 6·y = 9...(1)

x - 2·y = 3...(2)

The solution of a system of two linear equations with two unknowns can be found graphically by plotting the two equations and finding the coordinates of the point of intersection of the line graphs

Making 'y' the subject of both equations gives;

For equation (1);

3·x - 6·y = 9

3·x - 9 = 6·y

y = x/2 - 3/2

For equation (2);

x - 2·y = 3

x - 3 = 2·y

y = x/2 - 3/2

We observe that the two equations are the same and will have an infinite number of solutions

Given the function g(x) = x^3 − (8+1)x^2-4(9+2)x+(5x2-1) determine where the function is quickly(slowly) increasing (decreasing)
Elenna [48]

Answer:

hence g(x) is increasing at point x= 3+14i,3-14i

Step-by-step explanation:

given, g(x)=x^3-(8+1)x^2-4(9+2)x+5x2-1

         g(x)=x^3-9x^2-44x+10x-1

         g(x)=x^3-9x^2-34x-1

   \frac{\partial g(x)}{\partial x}=3x^2-18x-34

for increasing and decreasing function,

3x^2-18x-34=0

x=3+14i \geq0

x=3-14i \geq0

hence g(x) is increasing at point x= 3+14i,3-14i answer
