The set {(1, 2), (2, -3), (3, 4), (4, -5)} represents y as a function of x Question 2: The best statement describes the relation is "The relation represents y as a function of x, because each value of x is associated with a single value of y" ⇒ 3rd answer Question 4: There are missing options so we can not find the correct answer Question 5: The sets {(1 , 1), (2 , 2), (2 , 3)} and {(1, 2), (1, 3), (1, 1)} do not represent y as a function of x ⇒ 1st and 4th answers Step-by-step explanation: The relation is a function if each value of x has ONLY one value of y Ex: The set {(3 , 5) , (-2 , 1) , (4 , 3)} represents y as a function of x because x = 3 has only y = 5, x = -2 has only y = 1, x = 4 has only y = 3 The set {(4 , 5) , (-2 , 1) , (4 , 3)} does not represent y as a function of x because x = 4 has two values of y 5 and 3
The first thing you have to do is know the equation. The equation is a(1+p)^t. a= the amount of money p= the percent represented as a decimal and t=time ( the t is raised as an exponent) so, in this case, it is represented as 200(1+0.05)^2\ 200(1.05)^2 200(1.1025) 220.5 That is how much extra he would owe in interest fee's
