Question

The function f(x) = 2x² - 1 is/has A. neither symmetric about the y-axis nor has order 2 rotational symmetry about the originB. order 2 rotational 2 symmetry about the originC.oddD. symmetry about the y-axis

Answer 1

To determine The function f(x) = 2x² - 1 is/has

Option A is wrong cause it symmetric about y - axis

Option B is wrong cause it is not symmetry mm

Option C is wrong , its an even function

Option D is correct because it is symmetry about the y - axis

Hence the correct answer is Option D
