If the parent function f(x) = x2 is modified to g(x) = 2x2 + 1, which statement is true about g(x)?

sukhopar [10]

The right answer is A. It is an even function.

A function is said to be even if its graph is symmetric with respect to the $y-axis$ , that is:

$y=f(x) \ is \ \mathbf{even} \ if, \ for \ each \ x \ in \ the \ domain \ of \ f:\\ \\ f(-x)=f(x)$

Since:

$g(x)=2x^2+1 \ and \\ \\ g(-x)=2(-x)^2+1 \therefore g(-x)=2x^2+1 \\ \\ \therefore \boxed{g(x)=g(-x)}$

hydrophilic sequences are attracted by water and they remain in the aqueous enviornments on the two sides of the membrane. This diagram should clarify.
