Take into account that y-intercept is the point at which the curve crosses the y-axis.
As you can notice on the graph, the y-intercept is (0,4)
X intercept is the point at which the curve crosses the x-axis, In this case the curve do not cross the x-axis. Then, there are no x intercepts.
Then, the best description is:
x-intercepts: none
y-intercep: (0,4)
zeros: none
