Solution:

Given a triangle, ABC, with the coordinates point A below

[tex]A=(2,4)[/tex]

If the triangle is reflected over the y-axis first, the rule for the transformation is

[tex](x,y)\rightarrow(-x,y)[/tex]

The coordinates of point A becomes,

[tex](2,4)\rightarrow(-2,4)[/tex]

Then, the reflected over the x-axis, the rule for the transformation is

[tex](x,y)\rightarrow(x,-y)[/tex]

Then, the new point, A" will be

[tex](-2,4)\rightarrow(-2,-4)[/tex]

Thus, the answer is option d
