Answer:
Step-by-step explanation:
Next time, please share the possible answers (which here are graphs).
f(x)=x^3+x^2+x+1 builds upon the cubing function x^3, which starts in Quadrant III and continues into Quadrant I. f(x)=x^3+x^2+x+1 displays the same behavior. Note that if x = 0, f(0) = 1, so the y-intercept is (0, 1).
