$\bf\Huge\red{\mid{\overline{\underline{ ANSWER }}}\mid }$

➡️Given,

➡️A = {-4, 0, 1, 4}

➡️f(x) = x^2 – 1

➡️f(-4) = (-4)^2 – 1 = 16 – 1=15

➡️f(0) = (0)^2 – 1 = -1

➡️f(1) = (1)^2 – 1 = 0

➡️f(4) = (4)^2 – 1 = 16 – 1 =15

➡️Therefore, the set of ordered pairs = {(-4, 15), (0, -1), (1, 0), (4, 15)}

Answer 2

Answer:

➡️Given,

➡️A = {-4, 0, 1, 4}

➡️f(x) = x² – 1

➡️f(-4) = (-4)² – 1 = 16 – 1=15

➡️f(0) = (0)² – 1 = -1

➡️f(1) = (1)² – 1 = 0

➡️f(4) = (4)² – 1 = 16 – 1 =15

➡️Therefore, the set of ordered pairs = {(-4, 15), (0, -1), (1, 0), (4, 15)}✔
