Which graph represents an even function?

Answer
A
Image with description On a coordinate plane, the x and y axes range from negative 5 to 5 in increments of 1. The graph has a parabola that opens down with a vertex at (0 comma 4). It goes through (negative 2 comma 0) and (2 comma 0).
B
Image with description On a coordinate plane, the x and y axes range from negative 5 to 5 in increments of 1. The graph has a straight line with a negative slope. It goes through (negative 2 comma 4), crosses the y axis at (0 comma 2), and crosses the x axis at (2 comma 0).
C
Image with description On a coordinate plane, the x and y axes range from negative 5 to 5 in increments of 1. The graph has 2 curves, one in quadrant 1 and the other in quadrant 3. The curve in quadrant 1 goes through points (1 comma 5) and (5 comma 1). The curve in quadrant 3 goes through points (negative 5 comma negative 1) and (negative 1 comma negative 5).
D
Image with description On a coordinate plane, the x and y axes range from negative 5 to 5 in increments of 1. The graph has a curve in the shape of W. It has four x intercepts at (negative 2 comma 0), (negative 1 comma 0), (2 comma 0), (3 comma 0), and a y intercept at (0 comma 2 point 5). The curve has asymptotes at x equals negative 3 and x equals 4. The curve is labeled as g of x.
