Final answer:
The function with an x-intercept of 7 is y = 0x + 7.
Step-by-step explanation:
The equation that represents a function with an x-intercept of 7 is y = 0x + 7. In this equation, the coefficient of x is 0, meaning that x does not affect the value of y. The only term in the equation is 7, which represents the value of y when x is 0. Therefore, the x-intercept is at (7, 0) on the coordinate plane.
