Question

Given the piecewise function shown below, select all of the following statements that are true

Answer 1

A and C

Explanation:

A

when x = 2 , that is x > 1 then f(x) = x² , that is

f(2) = 2² = 4 ← True

B

when x = 5, that is x > 1 then f(x) = x² , that is

f(5) = 5² = 25 ≠ 1 ← not true

C

when x = 1 then f(x) = 5 , that is

f(1) = 5 ← True

D

when x = - 2 , that is x < 1 , then f(x) = 2x , that is

f(- 2) = 2(- 2) = - 4 ≠ 4 ← not true
