Respuesta :

f(x) means the value of y

The graph has a part down the x-axis which means f(x) < 0

The graph has another part over the x-axis which means f(x) > 0

The value of x for the negative part is from - infinity to 3

Then f(x) < 0 at the interval (-00, 3)

The value of x for the positive part is from 3 to infinity

then f(x) > 0 at the interval (3, 00)

Then the answer is C
