Question

problem number 8 please help i will upload it

Answer 1

what is \(f\) after you factor and cancel?

Answer 2

is it \(x^2-4x-5\)?

Answer 3

i got x^2-4x+5

Answer 4

no maybe \(x^2-4x+5\)

Answer 5

yup

Answer 6

ok then we want to solve
\[|x^2-4x+5-2|<0.01\] for \(x\)

Answer 7

\[|x^2-4x+3|<0.01\]
\[|(x-1)(x-3)|<.01\]
\[|x-1||x-3|<0.01\]

Answer 8

now if \(x\) is close to 3, then \(x-1\) is close to 2, so intuitively we can write \(2|x-3|<0.01\) which would mean \(|x-3|<0.005\)

Answer 9

should i slove it

Answer 10

solve

Answer 11

x<3.005,x<2.995

Answer 12

it says "within how many units"
i would say .005

Answer 13

ok then we want to solve
|x2−4x+5−2|<0.01
for x


How did u subtracted 2
