1.

Express the function f: A—R. f(x) = x2 – 1. where A = { -4, 0, 1, 4) as a set of ordered pairs.

Answer»

Answer:

ORDER pairs are (-4,15) (0,-1) (1,0) (4,15)

Step-by-step explanation:

f(X)= x^2-1

=-4^2-1

=15

(-4,15)

f(x)=x^2-1

=0^2-1

=-1

(0,-1)

f(x)=x^2-1

=1^2-1

=0

(1,0)

f(x)=x^2-1

=4^2-1

=16-1

=15

(4,15)
