Determine the zeros of the function f(x)= 3x^2-7x 1

There zeros of a function mean the x-intercepts. simpler way: At what x-values does the graph of the equation intersect the x-axis.

I don't know the if the last term of your function is +1 or -1 , so I did both for you using desmos graphing calculator. 

You can also use quadratic formula, and do the algebra, and see if you get the same answer.
