Question

Write a function to represent the set of ordered pairs

{(1,-2), (2,5),(3,24),(4,61)}

A: f(x) = -2x
B: f(x) = x^3 - 3
C: f(x) = x^2 - 3
D: f(x) = 5x^2 - 7

Answer 1

You will need to add them and you will get f=2x

Answer 2

i worked them all out its b

Explanation:

F(x) is basically y

(x, y)

if you plug in the x value and solve for each ordered pair the result should be the y value of each ordered pair

eg: (1, -2)

f(x)= x^3 - 3

f(1)= 1^3 - 3

f(1)= 1 - 3

f(1)= -2

when x was 1 y was -2, like the ordered pair
