We are given two functions. We can get the red function if we do the following transformations to the black function.
1. Translation 5 units to the left in the direction of the x-axis. This means that if the black function is f(x), then the transformed function is:

2. A reflection across the x-axis, this transformation is equivalent to multiplying or dividing y by -1, therefore we get:

Therefore, the red function is option B.
