Which best describes the end behavior of y=7x^2?

as x > 0 increases, f(x) decreases. as x < 0 decreases, f(x) decreases.

as x > 0 increases, f(x) increases. as x < 0 decreases, f(x) decreases.

as x > 0 increases, f(x) increases. as x < 0 decreases, f(x) increases.

as x > 0 increases, f(x) decreases. as x < 0 decreases, f(x) increases.
