Find the y-intercept of the polynomial function.
-$$f ( x ) = x ^ { 3 } + x ^ { 2 } + 1$$
A) origin symmetry
B) $y$-axis symmetry
C) neither

Question

Quizplus · Accepted Answer

The y-intercept of a polynomial function is found by evaluating the function at $x = 0$. For $f(x) = x^3 + x^2 + 1$, $f(0) = 0^3 + 0^2 + 1 = 1$, which is a point on the graph, not related to symmetry. The question's choices pertain to symmetry, not the y-intercept, and this function does not exhibit origin or y-axis symmetry.
