Determine the domain of the function. f(x)=4/x^2

1 answer:

3 0

Since x can be any value as long as the denominator equals 0 (it doesn't matter if it's positive or negative), we have to figure out when x^2=0, which is when x=0. Therefore, the domain is (-inf, 0) U (0, inf)

Answer:

e,q,u,a,t,i,n & EQUATIONYL

Step-by-step explanation:

K∩L:

First write both the words, equation and inequality down.

E Q U A T I O N

I N E Q U A L I T Y

You can see EQUATIN repeats in both of the words.

K∪L:

First write both the words, equation and inequality down.

E Q U A T I O N

I N E Q U A L I T Y

This time just write down all the letters EXCEPT the ones that repeat. EQUATIONYL

Part C Now try this one. Write a description of the partitioned function using known function types, including transformations.

Sever21 [200]

Answer:

Following are the function description to the given question:

Step-by-step explanation:

In the given-question, three functions are used, that can be defined as follows:

In function 1:

This function is also known as the modulus on the absolute value function, for example:

$f(x)=| x| \left \{ {{x , \ \ \ x>0} \atop {-x, \ \ \ \x$

In the given in the above graph, that is $f(x) = -x , \ \ x$

In function 2:

In this function, It is an algebraic function that is $y=x^2$

It is also a part of the quadratic polynomial function, and its value is $y=x^2 , \ \ \ x> 0$

In function 3:

In this function, it is the cubic polynomial equation that's value is $y=x^3$

In the graph its value is:

$y=-x^3\\\\and \\ \\\to y= f(x) \\\\ \to y=-f(x)\\$

Factorise fully 3x-9x^2

artcher [175]

Answer:

$3x(1 - 3x)$

Step-by-step explanation:

We can factor the expression by using the common factor.

Pull out 3x from the expression.

$3x - 9 {x}^{2} \\ 3x(1 - 3x)$

Common Factor is similar to dividing by the term we pull out. When we pull out the term, we divide the whole expression and keep the term out of the expression.
