Question

5. Function f is defined by the equation f(x) = x².

a. What is (2)?
b. What is (3)?
c. Explain why f(2) + f(3) ‡ f(5).

Answer 1

f (2) = 2^2 = 2 * 2 = 4

f (3) = 3^2 = 3 * 3 = 9

f(2) + f(3) = 4 + 9 = 13

f (5) = 5^2 = 5 * 5 = 25

13 does not equal 25

a. 4

b. 9

c. f(2) + f(3) ‡ f(5) can be stated as 13 does not equal 25
