What is the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4?

Umnica [9.8K]

The average rate of change of function is 72.

<u>SOLUTION: </u>

Given that, we have to find the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4

Use the slope formula to find the average rate of change:

$\begin{array}{l}{m=\frac{y 2-y 1}{x 2-x 1}} \\\\ {m=\frac{f(4)-f(2)}{4-2}} \\\\ {m=\frac{f(4)-f(2)}{2}}\end{array}$

To simplify this, we need to find values of f ( 4 ) and f ( 2 ) :

$\begin{array}{l}{f(4)=2 x(3)^{4}=2(81)=162} \\\\ {f(2)=2(3)^{2}=2(9)=18} \\\\ {m=\frac{162-18}{2}} \\\\ {m=\frac{144}{2}} \\\\ {m=72}\end{array}$

dillon pays x dollars to get a haircut. he gives the stylist a 15% tip. the expression representing his total cost is x + 0.15x

bagirrra123 [75]

Answer:

B) 1.15x, adding 15% to the cost of haircut is same as to multiply cost by 1.15

Step-by-step explanation:

Given expression = x + 15% of x

x + (15/100) x = x + 0.15x

= (1+ 0.15) x = 1.15x

15% = 0.15 , added to x = 1.15x
