Consider the polynomial f(x) = x 3 −3x 2 +x−3. One root of this polynomial is r = 3. Now consider the polynomial fϵ(x) = (1 + ϵ)x 3 − 3x 2 + x − 3, where ϵ is small.(a) Using the sensitivity formula for rootfinding, predict the shift in the root ∆r from r = 3 as a function of ϵ. What does this tell you about how errors in the coefficient of the cubic term of the input (backward error) are magnified in the output of rootfinding (forward error)

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
