Which function is a one-to-one function? h(x) = -(x - 5)^2 + 3
b(x) = x^3 – 5
z(x) = x^4 + 2
q(x) = – |x – 8| – 4

idk

step-by-step explanation:

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
