Question

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

Answer 1

B and D

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

Option B and D

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
