For the graphed function f(x) = (4)x − 1 + 2, calculate the average rate of change from x = 1 to x = 2.
lorasvet [3.4K]

Average rate of the function: 3

Step-by-step explanation:

The function in this problem is

f(x)=4^{x-1}+2

The average rate of change of a function over an interval (x_1,x_2) is given by

r=\frac{f(x_2)-f(x_1)}{x_2-x_1}

where

f(x_1),f(x_2) are the values of the function calculated in x_1,x_2 respectively

For the function in this problem we have:

x_1=1, so

f(x_1)=f(1)=4^{1-1}+2=4^0+2=1+2=3

x_2=2, so

f(x_2)=f(2)=4^{2-1}+2=4^1+2=4+2=6

So, the average rate of change is

r=\frac{6-3}{2-1}=\frac{3}{1}=3

#10<br> Write the equation of the given circle.<br><br> center (-2, -2)<br> radius of 6
Roman55 [17]
(x - h)^2 + (y - k)^2 = r^2

h = -2
k = -2
r = 6

(x - (-2))^2 + (y - (-2))^2 = 6^2

(x + 2)^2 + (y + 2)^2 = 6^2

(x + 2)^2 + (y + 2)^2 = 36. your answer

hope this helped, blessings! :)
