Answer:

Interval Slope of secant lines

[1,2] 113.000

[1, 1.5] 75.000

[1, 1.1 ] 51.960

[1, 1.01] 47.482

[1, 1.001] 47.048

Step-by-step explanation:

From the question we are told that

The function is
`f(x) =  16x^3 -x`

Now considering the intervals

For [1, 2]

The slopes of secant lines is mathematically represented as

`( f(2) - f(1))/(2-1)  =  (16(2)^3 - 2 - [16(1)^3 -1] )/(2-1 )  =  113.000`

For [1, 1.5]

The slopes of secant lines is mathematically represented as

`( f(1.5) - f(1))/(1.5-1)  =  (16(1.5)^3 - 1.5 - [16(1)^3 -1] )/(1.5-1 )  = 75.000`

For [1, 1.1]

The slopes of secant lines is mathematically represented as

`( f(1.1) - f(1))/(1.1-1)  =  (16(1.1)^3 - 1.1 - [16(1)^3 -1] )/(1.1-1 )  = 51.960`

For [1, 1.01]

The slopes of secant lines is mathematically represented as

`( f(1.01) - f(1))/(1.01-1)  =  (16(1.01)^3 - 1.01 - [16(1)^3 -1] )/(1.01-1 )  =47.482`

For [1, 1.001]

The slopes of secant lines is mathematically represented as

`( f(1.001) - f(1))/(1.001-1)  =  (16(1.01)^3 - 1.001 - [16(1)^3 -1] )/(1.001-1 )  =47.048`
