For the function f(x) = 6x+1 , evaluate and simplify the difference quotient

For a given function f(x), we define the difference quotient as:

\frac{f(x + h) - f(x)}{h}

We will get that the difference quotient is equal to 6.

Here we have the function:

f(x) = 6*x + 1

The difference quotient will be:

\frac{f(x + h) - f(x)}{h} = \frac{6*(x + h) + 1 - (6*x + 1)}{h}

Now let's simplify it:

\frac{6*(x + h) + 1 - (6*x + 1)}{h}  =  \frac{6*x + 6*h + 1 - 6*x - 1}{h}  = \frac{6*h}{h} = 6

Now, we also are asked to evaluate it, but as you can see, the <u>difference quotient is constant</u>, thus we can't actually <u>evaluate it, as it will always be equal to 6.</u>

The number of people employed as medical assistants in a country was 373 thousand in 2003. By the year 2013​, this number is exp
Troyanec [42]

a) The linear function is: y = 21.8x + 373

b) The estimate for the number of people employed in 2012 is of 569.2.

-----------------------------

A linear function has the following format:

y = mx + b

In which

  • m is the slope, that is, how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

-----------------------------

Item a:

  • During the first year of observation, the number of people, in thousands of dollars, was of 373. Thus, the y-intercept is b = 373
  • In 10 years, it changed from 373 to 591, thus, the slope is:

m = \frac{591 - 373}{10} = 21.8

The function is:

y = 21.8x + 373

-----------------------------

Item b:

2012 is 9 years after 2003, thus, this is y(9)

y(9) = 21.8(9) + 373 = 569.2

The estimate for the number of people employed in 2012 is of 569.2.

50 POINTS!!! i WILL GIVE BRAINLISET IF YOU ANSWER FAST Find the domain for the rational function f of x equals quantity x minus
S_A_V [24]

Answer:

(−∞, 2)∪(2, ∞)

Step-by-step explanation:

Domain is all the values that "x" can be

since finding all the values which "x" can be is too hard we will find out the values which "x" can't be- this means equating the denominator to "0" so that the function will be undetermined:

f(x)=\frac{x+1}{x-2}f(x)=

x−2

x+1

since we need the denominator to be "0" we must use the opposite of (-2) which is "2" so we will substitute "2" in the place of "x"f(2)=\frac{2+1}{2-2}f(2)=

2−2

2+1

- the function is now "undetermined" since nothing can be divided by 0 we need to write our answer in proper domain/range format

-Hope this helps!
