Which expression below gives the average rate of change of the function h(x)=4^(x+2)+7 on the interval –3 ≤ x ≤ 5?

viktelen [127]

Answer:

$\frac{4^8-1}{32}$

Step-by-step explanation:

$h(x)=4^{(x+2)} +7$

We know that formula for average rate of change of a function from a to b is

$\frac{f(b)-f(a)}{b-a}$

Here f equals h and a =-3 b=5

h(a) = $4^{5+2} +7 = 4^7+7$

and

h(b) = $4^{-3+2} +7 = \frac{1}{4} +7$

h(b)-h(a) = $4^7-\frac{1}{4} =\frac{4^8-1}{4}$

b-a = 5-(-3) =8

Hence average rate of change is

$\frac{4^8-1}{4}(\frac{1}{8} )=\frac{4^8-1}{32}$

Mrrafil [7]

Use these conversions:

1 foot = 12 in

1 mile = 5280 feet

67000 in * [1 ft /12 in] * [1 mile/5280 ft]

Then the answer is the option c.
