Average rate of change of the function $=\frac{75}{2}$

Solution:

Given function: $f(x)=5(2)^{x}$ from x = 1 to x = 5

Substitute x = 1 and x = 5 in f(x).

$f(1)=5(2)^{1}=10$

$f(5)=5(2)^{5}=160$

Let us find the average rate of change of the function.

Average rate of change

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

Here a = 1 and b = 5.

$$=\frac{f(5)-f(1)}{5-1}$

Substitute f(5) and f(1).

$$=\frac{160-10}{4}$

$$=\frac{150}{4}$

$$=\frac{75}{2}$

Average rate of change of the function $=\frac{75}{2}$

How to solve 30+(4x+2)=8+6x)

Gennadij [26K]

Answer:

Step-by-step explanation:

30+(4x+2)=8+6x

30+4x+2=8+6x

32+4x=8+6x

32=8+6x-4x

32=8+2x

2x=32-8

2x=24

x=24/2

x=12

Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.

zalisa [80]

<h3>Answer: C) 4</h3>

All points on the blue curve f(x) are shifted up 4 units to get corresponding points on the red curve g(x). For example, the point (0,-3) moves up 4 units to (0,1).

g(x) = f(x)+k

g(x) = f(x)+4

Please help me this question

Annette [7]

Step-by-step explanation:

Hey there!

The given point is (8,-3) as (x1,y1) and slope (m) = -3/4.

Note: use one point formula for finding the equation.

$(y - y1) = m(x - x1)$

Put all values.

$(y + 3) = - \frac{ 3}{4} (x - 8)$

Simplify it.

$(y + 3) = - \frac{ 3}{4} x - 8 \times - \frac{3}{4}$

$(y + 3) = - \frac{3}{4} x + 6$

$y = - \frac{3}{4} x + 6 - 3$

$y = - \frac{3}{4} x + 3$

Therefore, the equation is; y = -3/4x+3.

Hope it helps...
