i'll pose this to you
for this example the zero's lie on the black does, or where the graph intersects the x-axis i.e when f(x)=0 or y=0
so in this question , we need to find the position of points where 0 lies in
so find possible y values where zero lies between them
for corresponding x values
you don't need to graph it, we can just visually look at it. perhaps we shall write these values in a table.
so in which points does 0 lie in the y-coordinate?
I see thanks !!
