We can split it up into

I see you were supposed to use synthetic division
not sure what the 'related function is'
but as |x| approaches positivie infinity, y approaches positive infinity
as |x| approaches negative infinity, y approaches positive infinity
for the original function
as x approaches positivie infinity

approaches positive infinity
as x approaches negative infinity

approaches positive infinity
this is due to the x^2 term making it positive
Because you add both negative x’s which is -2 and add the -6 in the right side so then it’s -2x=4
Divide and you get x=-2
Answer:
Harriet's estimated length is between 44.1 inches and 47 inches.
Step-by-step explanation:
Let the error be x.
so, x<4%
Now, if error is 1%
45 1/2 + 1% of 45 1/2
or, 91/2 + 1/ 100 × 91/2
= 46
Now,
45 1/2 - 1% of 45 1/2
or, 91/2 - 1/100 × 91/2
= 45.1
Now,
if error is 3%
45 1/2 + 3% of 45 1/2
or, 91/2 + 3/100 × 91/2
= 47
OR
45 1/2 - 3% of 45 1/2
= 91/2 - 3/100 × 91/2
= 44.1
