The average r. of c. of a function f(x) on an interval [a,b] is:

  f(b) - f(a)
--------------
    b-a

You'll need to apply this to all four of the given functions.

First function:  f(x) = x^2 + 3x
a= -2; b= 3

Then the ave. r. of c. for this function on this interval is:

    18  - (-2)            20
------------------ = ---------- = 4.  y increases by 4 for every unit increase in x.
      3-(-2)                5

Do the same thing for the other 3 functions.

Then arrange your four results in descending order (greatest to least).

An article reports "attendance increased 5% this year, to 4948." What was the attendance before the increase? (Round your answer
snow_tiger [21]

Answer: The attendance before the increase was 4712.

Step-by-step explanation:

Let the attendance before the increase be 'x'.

Rate of increment = 5%

so, Attendance after increment becomes

\dfrac{100+5}{100}\times x = 4948\\\\\dfrac{105}{100}\times x=4948\\\\1.05\times x=4948\\\\x=\dfrac{4948}{1.05}\\\\x=4712.38\\\\x=4712

Hence, the attendance before the increase was 4712.

Which phrase best describes f(x) graphed on the on the coordinate plane below?
Gennadij [26K]

We know that

Odd function:

When we have

f(-x)=-f(x)

Even function:

When we have

f(-x)=f(x)

We will reflect our graph about y-axis

When we reflect about y-axis

we will get same graph except same curve moves to bottom

so, this is odd function

The Patel family has a disposable income of $90,000 annually. Assume that their marginal propensity to consume is 0.8 (the Patel
Marrrta [24]
To get the annual spending of Patel family, we will need to add the amount of consumption according to their marginal propensity to consume and their autonomous consumption spending. with the formula

Consumption= Autonomous consumption + (Disposable incomeXmarginal propensity )
Where
Autonomous consumption = $10000
Disposable income = $90000
margina propensity = 80%
substitute all given value to get the consumption
Consumption =  $82,000
Patel family annual consumer spending is $82000.
