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

xz_007 [3.2K]

For the function
f(x) = 4^(x-1) +2
the average rate of change on the interval [1, 2] is found by computing
(f(2) - f(1))/(2 - 1)
= ((4^1+2) - (4^0+2)/1
= (6-3)
= 3

$y\leq-x-1\\\\y=-x-1\\for\ x=-1\to y=-(-1)-1=1-1=0\to(-1;\ 0)\\for\ x=0\to y=-0-1=-1\to(0;-1)$

$y\geq2x+4\\\\y=2x+4\\for\ x=-2\to y=2\cdot(-2)+4=-4+4=0\to(-2;\ 0)\\for\ x=0\to y=2\cdot0+4=0+4=4\to(0;\ 4)$
