Answer:
A. g(x) = - x²
Step-by-step explanation:
f(x) reflex over x-axis: g(x) = - f(x)
Using translation concepts, it is found that the equation of g(x) is given by:
A. g(x) = -x².
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the parent function f(x) = x² was reflected over the x-axis, that is, it was multiplied by -1, hence the equation for g(x) is given by:
g(x) = -f(x) = -x².
Which means that option A is correct.
