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

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

the correct answer is 5 6 and 7

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
