Answer:
No
(-4,-1) and (3,4]
(-4,0), (-1,0) and (3,0)
Step-by-step explanation:
The graph below is of a polynomial. Its shape indicates an odd degree since it starts down and ends up. It has 3 roots where f(x) = 0. These roots are the x-intercepts. They are (-4,0), (-1,0) and (3,0). The other values of the function can be described based on their location above or below the x-axis. Any part of the graph above the x-axis is positive and greater than 0. Any part of the graph below the x-axis is negative and less than 0.
On this graph, between x values [-5,-4) and (-1,3) the function values are negative or below 0. Between (-4,-1) and (3,4] the function values are positive or above 0. This means f(1) is in interval (-1,3) so the function value is negative and not positive.
