Question
Use the Vertical Line Test to determine whether $y$ is a function of $x$.$$y=\frac{1}{2} x^{3}$$(GRAPH CANNOT COPY)
Step 1
If we can draw any vertical line that intersects a curve more than once, then the curve does not represent a function. If all vertical lines intersect a curve at most once, then the curve does represent a function. Show more…
