Which statement is true about the graphed function?

f(x) < 0 over the interval (–∞, –4)
f(x) < 0 over the interval (–∞, –3)
f(x) > 0 over the interval (–∞, –3)
f(x) > 0 over the interval (–∞, –4)

F(x) >0 over the interval (-∞, -4)

Step-by-step explanation:

The function y= f(x) shows the different values that y takes, when x varies. In the picturewe see that y takes possitive values (y>0) when x < -4 , point from which the function y takes negative values. Then y= f(x) >0 from -∞ to -4, which means that y= f(x) >0 over the interval (-∞, -4).

The answer is D

Step-by-step explanation:

Hopefully this helps you :)

pls mark brainlest  ;)

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
