**Interpretation**:

The equation of the function

The parabola opens upward.

The

Substitute

Therefore, x- intercept is 0.

The y- intercepts are the points on x -axis where the graph of the equation intersects the y -axis.

Substitute

Therefore, y- intercept are is 0.

Therefore, the equation

Recall that the function is symmetric with respect to the y -axis, when x is replaced by -x .

Replace x by

Therefore, the equation

Therefore, the function is open downward with axis as y -axis.
