A logistics manager uses a quadratic function to model the fuel efficiency of a delivery fleet based on speed. To find the 'zero-efficiency' points where the graph crosses the horizontal axis (the x-intercepts), which algebraic step is required?

A landscape architect uses a quadratic equation to model the path of water from a fountain. Match the type of intercept the architect needs to find with the correct algebraic procedure.

A small business owner uses a quadratic equation to model the daily operating costs of a new storefront. To find the y-intercept, which represents the fixed costs on day zero, the owner should substitute 0 for y and solve the equation for x.

A marketing specialist is analyzing a campaign's effectiveness using a parabolic model $y = ax^2 + bx + c$. To find the points where the effectiveness is zero (the x-intercepts), the specialist follows a standard algebraic procedure. Arrange the following steps in the correct order.

Calculating X-Intercepts for a Parabolic Model

A small business owner uses a quadratic model $y = ax^2 + bx + c$ to predict the monthly profit ($y$) based on the number of years in operation ($x$). To find the 'starting profit' on the day the business opened (the y-intercept), the owner must substitute the value ____ for the variable $x$.

A structural engineer is analyzing a parabolic bridge arch modeled by the equation $y = ax^2 + bx + c$. When identifying the x-intercepts (the points where the arch meets the horizontal foundation), which coordinate must always be equal to zero at those points?

A human resources manager uses a parabolic function to model the number of employee departures at a new branch over time. If the manager determines that the y-intercept of this model is 12, which ordered pair correctly identifies this point on a coordinate graph?
