Answer
(a) x-intercept
Work Step by Step
We are asked: "The graph of a function $y = f(x)$ can have more than one of which type of intercept?"
The correct answer is: (a) x-intercept. Graphs of functions can have multiple $x$ intercepts because we can have multiple $x$ values for the same $y$ value (but the opposite is not true, so we cannot have multiple $y$-intercepts).
