Answer:

\displaystyle{ -  \frac{9}{6} + ( -  \frac{3}{5} ) }

\displaystyle{ -  \frac{9}{6} -  \frac{3}{5}  }

  • Multiply the numerator and denominator to make it equivalent:

\displaystyle{ =  -  \frac{9}{6}  =  -  \frac{9 \times 5}{6 \times 5}  =  -  \frac{45}{30} }

\displaystyle{ =  \frac{3}{5}  =  \frac{3 \times 6}{5 \times 6}  =  \frac{18}{30} }

So,

\displaystyle{ =  -  \frac{45}{30}   -  \frac{18}{30}  = -   \frac{45 - 18}{30} =  -  \frac{37}{30}  }

F(x)=x^3 −9x <br> What is the average rate of change of over the interval [1,6]?
Inga [223]

Answer:

34

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

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

Here [ a, b ] = [ 1, 6 ], thus

f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162

f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8

average rate of change = \frac{162-(-8)}{6-1} = \frac{170}{5} = 34
