Answer:
See below
Step-by-step explanation:
Expand L side to get
4n -12 -2n < -10 + 2n simplify L side
2n -12 < -10 +2n subtract 2n from both sides
<u>-12 < -10 </u> <===== so the equation is true for ALL n
(-∞ , + ∞ )
The end behavior is that as the value of x increases the value of function increases.
<h3>How to get the graph of a function?</h3>
A) We want to completely factor; f(x) = 2x² - x - 10
⇒ f(x) = 2x² - 5x + 4x - 10
⇒ 2x(x + 2) - 5(x + 2)
⇒ (2x - 5)(x + 2)
B) The x-intercept occurs at y = 0. Thus;
(2x - 5)(x + 2) = 0
x =5/2 and x = -2
C) f(x) = 2x² - x - 10
Thus, the end behavior is that as the value of x increases the value of function increases.
D) The graph steps has been attached

Answer:
b is the answer.
Step-by-step explanation:
cost of cartridges = number of cartridges x cost per cartridge
= 35x
total cost = cost of printer + cost of cartridges
= 100 + 35x
= 35x + 100
