step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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
