Find the average rate of change of f(x)=2x^2-7x from x=2 to x=6
scoundrel [369]

Answer:

Step-by-step explanation:

The average rate of change of a function f between a and b (a< b) is :

R =[f(b)-f(a)] ÷ (a-b)

●●●●●●●●●●●●●●●●●●●●●●●●

Let R be the average rate of change of this function

f(6) = 2×6^2 - 7×6 = 72-42 = 30

f(2) = 2×2^2 - 7×2 = 8-14 = -6

R = [f(6) - f(2)]÷ (6-2)

R = [30-(-6)] ÷ 4

R = -36/4

R = -9

■■■■■■■■■■■■■■■■■■■■■■■■■

The average rate of change of this function is -9

17) x-8=11

18) 9-x=5

19) x+6=7

20) x+(-4)=-18

Step-by-step explanation:

17) The difference between a number and 8 is 11

Let number = x

then the equation will be:

x-8=11

Solving:

x-8=11

x=11+8\\x=19

18) Nine less than a number is five.

Let number = x

then the equation will be:

9-x=5

Solving:

9-x=5\\-x=5-9\\-x=-4\\x=4

19) Seven is equal to a number plus 6

Let number = x

then the equation will be:

x+6=7

Solving:

x+6=7\\x=7-6\\x=1

20) The sum of a number and -4 is -18

Let number = x

then the equation will be:

x+(-4)=-18

solving:

x+(-4)=-18\\x-4=-18\\x=-18+4\\x=-14
