Find the average rate of change<br> f(x)=x^2−6x+8 when x2=1 and x1=3

sergeinik [125]

Answer:

Average rate of change for given function is: -2

Step-by-step explanation:

Given function is:

$f(x)=x^2-6x+8\\x_12= 1\\x_1 = 3$

In order to find the rate of change, we have to find the value of function on x1 and x2

So,

$f(x_1) = (3)^2-6(3)+8 = 9-18+8 = -1\\f(x_2) = (1)^2-6(1)+8 = 1-6+8 = 3$

The formula for finding the rate of change is:

$Rate\ of\ change = \frac{f(x_2)-f(x_1)}{x_2-x_1}$

Putting the values, we get

$=\frac{3-(-1)}{1-3}\\=\frac{3+1}{-2}\\=\frac{4}{-2}\\= -2$

Hence,

Average rate of change for given function is: -2

What is the value of x in the equation 0.75x+3=6(x-3)?

cluponka [151]

Answer:

x = 4

Step-by-step explanation:

Given

0.75x + 3 = 6(x - 3) ← distribute

0.75x + 3 = 6x - 18 ( subtract 0.75x from both sides )

3 = 5.25x - 18 ( add 18 to both sides )

21 = 5.25x ( divide both sides by 5.25 )

4 = x

(multiple choice) What is the excluded value of this?

Mrac [35]

$\frac{x-2}{x-6}$

There's no division by zero, so x can't be a value which x - 6 = 0

x - 6 ≠ 0

x ≠ 6
