is a function.
Expert Solution
Step 1
It is relatively easy to determine whether an equation is a function by solving for y.
A given relation y=f(x) is a function if there is one and only one corresponding y-value for an x-value.
Vertical line test
If any vertical line drawn parallel to the y-axis intersects the graph of the equation more than once for any value of x then the graph does not represent a function.
