<h3>What are irrational numbers?</h3>
Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, x/y where x and y are integers.
In other words, an Irrational Number is a real number that cannot be written as a simple fraction.
For example π = 3.1459....
π cannot be written as a fraction or ratio.

Answer:
A) F(x) = 50 + ( x - 10 )*9
B) Graph
C) lim ( x ⇒ 10) F(x) = 50
Step-by-step explanation:
A) F(x) = 50 + ( x - 10 )*9 since the first 10 hours are included in initial fee
B) In Annex
C) lim (x ⇒ 10) F(x) = 50 + ( 10 -10)*9
lim ( x ⇒ 10) F(x) = 50 + 0
lim ( x ⇒ 10) F(x) = 50
Answer:
Vertex: (2, -1)
Zeros: 1 and 3
End behavior: both are inf
Step-by-step explanation:
examine the graph carefully. The vertex is the center of the line. Zeros is where the line touches the x -axis
