Final answer:
None of the given functions have an x-intercept at (1,0).
Step-by-step explanation:
In order to determine which functions have an x-intercept at (1,0), we need to find the functions that satisfy the condition where y = 0 when x = 1. The only function that satisfies this condition is the function with the equation y = -3x. When x = 1, y = -3(1) = -3, which is not equal to 0. Therefore, none of the given functions have an x-intercept at (1,0).1
