What is the average rate of change for this quadratic function for the interval from x = 0 to x = 2 ?

vagabundo [1.1K]

Answer: -2

Step-by-step explanation: The average rate of a function f(x) from x=a to x=b is given as:

Clearly we are asked to find the average rate of change from x=0 to x=2.

i.e. a=0 and b=2

Also, from the graph it could be observed that:

f(0)=1

and f(2)=-3

Hence, the average rate of change is calculated as:

Hence, the average rate of change for this quadratic function for the interval from x = 0 to x = 2 is:

The subtraction function

$(k-x)(x)$

is defined as the subtraction of the two equations, representing each function:

$(k-h)(x)=k(x)-h(x)$

So, we have

$(k-h)(x)=k(x)-h(x)=14x-2-(2x^3+4x-8)=-2x^3+10x+6$

Please help me with this

kirill [66]

Answer:

15/2 or 7.5

Step-by-step explanation:

$5/6 (x + 1/2 + 4)$

distribute 5/6 to each number

$5/6x + 5/12 + 10/3$

change the fraction 10/3 so that it will have the same denominator as 5/12

$\frac{10}{3} *4$ = 40/12

$5/6x + 5/12 + 40/12\\5/6x + 45/12$

divide both sides by 5/6

$x = 9/2$

$5/6*9/2+5/12+10/3 = \frac{15}{2}$
