Find the zeros of the function. f(x)= cube root of x

The only zero of this function is (0, 0). this is where the graph goes through the x-axis.  It's the only place, actually. So the zero is z = 0, and when x = 0, y also happens to equal 0

Cis your correct answer

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
