Answer:
c
Step-by-step explanation:
In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.
However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).
Multiply both sides by 7. w=<span>105</span>
<span>As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) increases.</span>
