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:
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
