EXPLANATION
The portion of the graph that is above the x-axis is considered positive.
From the graph the curve is above the x-axis on the interval
(-∞,-2) and (0,4).
The first and second options are correct.
Answer:
11x^2+x-1
Step-by-step explanation:
To do so, just add the two polynomials together as such:
11x^2 +0x-5 plus
0x^2+1x-4 equals
11x^2+x-1
12x is the correct answer
