The true statement, regarding the signal of the graphed function, is given by:
F(x) > 0 over the interval (–∞, –4).
<h3>When a function is positive and when it is negative?</h3>
Looking at it's graph, we have that:
- The function is positive when it is above the x-axis.
- The function is negative when it is below the x-axis.
Researching this problem on the internet and looking at the graph of the function, the function is negative for <u>all values to the right of x = -4</u>, and positive to the left, hence the correct statement is given by:
F(x) > 0 over the interval (–∞, –4).

Answer:
A
Step-by-step explanation:
Deshaun charges $40 per hour.
So if Deshaun and Silvio work for 5 hours, then it would be $40(5) which would be more expensive than Silvio's with $60 + 20(5). Silvio gets $60 with $20 per hour.
Deshaun would get $200 while Silvio would get $160.
