Answer:
Option (C)
Step-by-step explanation:
The given graph represents the relation between her profit and the price charged.
x-intercepts from the graph are at,
x = 20 and x = 65, which show the selling prices.
x-intercepts means y = 0
And y = 0 represents no profit no loss.
When we summarize these data,
zeros : x = 20 and x = 65
These are the selling prices that will give her neither profit nor loss.
Therefore, Option (C) will be the answer.
Answer:
f(x) = 1/ x² - 3
f(3) = 1 / 3²- 3
=1/6
f(2+h) = 1 / (2+ h) ² - 3
= 1 / 4 + 4h + h² - 3
therefore...
f(2 + h) = 1 / 1 + 4h + h²

3/4 is .75
There are 60 minutes in an hour
Multiply .75 by 60 to get 45 minutes
