yesss

there’s absolute value signs, so flip everything above the x axis to replace everything below. then, the domain of this new thing is the range of g(|x|)

this paper ruined my life i was so close to getting 70/70 for the first time in my life and then this question came along

ohh ic ic but then wouldn't it no longer have an inverse fucntion, like it would fail the HLT

nope, try draw it, it still passes the HLT fine

No, the answer B is correct.

Sketch the inverse by reflecting the given graph in y = x. That's g(x)

g(|x|) is the same as g(x) for x > 0... this starts at (0, a) and decreases to (d, b)... but g(|x|) is also even, so g(|x|) starts at (-d, b), rises to a y-intercept of (0, a), then decreases back to (d, b). Its domain is [-d, d] and its range is [b, a].
