What are the zeros of a given graph? And how do you distinguish them?

I have attached an image of a function graphed. How would I determine the zeros of this graph, and/or approximate the solutions based off of this graph?

you look where the graph crosses the x-axis, i.e. where $y=0$

That's why they are called "zeroes"

Looking at this graph it looks like they are at

$x=\dfrac 3 4$

$x = -5\dfrac 3 4$
