Question

Given the piecewise function shown below select all of the statements that are true please help

Answer 1

Answer:

B  and D

Step-by-step explanation:

B  because  x > 0 , so f(x) = x^2 = 3^2 = 9

D because x  is also > 0 and f(2) = 2^2 = 4

Answer 2

Answer:

Option B and D

Step-by-step explanation:

Option A ⇒ for x = 4

                    f(x) = x² when x > 0

                    f(4) = 4²

                          = 16 ≠ 0   so incorrect option

Option B ⇒ for x = 3

                    f(x) = x²  when x > 0

                    f(3) = 3²

                     = 9    so the option is correct.

Option C ⇒ for x = 1

                    f(x) = x²    when x > 0

                    f(1) = 1 ≠ (-3)   so the option is incorrect.

Option D ⇒ for x = 2

                    f(x) = x²   when x > 0

                    f(2) = 2²

                          = 4     so the option is correct

Option B and D is the answer
