Answer:
C. symmetrical to the y-axis
Step-by-step explanation:
You want to know what symmetry the function f(x) = 2x⁴ +x² -6 has.
Even function
All of the exponents are even, so the polynomial function f(x) is an even function. That means f(x) = f(-x), and the graph is symmetrical about the y-axis, choice C.
