To find the vertex: Set the expression between the absolute value bars equal to zero, that's just the red part below:Now find the y-value that corresponds to that value of x: So the vertex is the point } So we plot that point: Now find and plot one point on each side of that point: So choose x to be 1 less than 3, which is 2, Substitute in: So we plot the point Next choose x to be 1 more than 3, which is 4, Substitute in: So we plot the point Then we draw the v-shaped graph: That's it.
