SOLUTION: The graph of a linear function, f, is shown. https://ibb.co/fSmLkg8 What is the zero of f? A. -3 B. 3 C. 2 D. -6

 

That's the same as asking "What value of x causes y to be 0?

That's also the same as asking "At what x-value does the point on the x-axis 
have where the graph crosses it?"

Or, what is the x-intercept?

It's a look-and-see question. So look and see.
