Melinda has shown that a function, f(x), increases by 4 for every unit in the domain. what does this prove?

the function f(x) is an arithmetic sequence.

the function f(x) is a geometric sequence.

the function f(x) is not a sequence.

this does not prove anything.

Option 1 is correct that is the function f(x) is an arithmetic sequence.

Step-by-step explanation:

We have been given the information that function is increasing by 4 for every unit in the domain.

That means difference between the consecutive terms will be same that is common difference exists

For example:

we have a function f(x)=x

Since, it is increasing by 4 for every unit means function becomes x,x+4,x+4+4

The common difference is 4.

Hence, the function f(x) is an arithmetic sequence.

therefore, option 1 is correct.

By definition, we have to:

An arithmetic sequence is a sequence of numbers that increases or decreases by a constant amount each term.

We can write a formula for the term n of an arithmetic sequence in the form:

an = d * n + c

Where,

n: domain variable

c: initial value

d: constant term.

For this case we have:

an = 4 * n + c

The function f (x) is an arithmetic sequence.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

sorry can't

i googled though and something came up but it was in science langueage not common english sooo
