An architectural designer is modeling a curved support beam that follows the path of a horizontal parabola. To find the $x$-intercept of the beam—the point where it crosses the horizontal $x$-axis—which algebraic step should the designer perform first in the equation?

A technician at a solar energy company is calibrating a horizontal parabolic trough modeled by an algebraic equation. To find the $y$-intercepts of this horizontal parabola, the technician should substitute ${}0$ for $y$ in the equation and solve for $x$.

A quality control technician is verifying the alignment of a horizontal parabolic reflector on a coordinate grid. To document the component's exact position, the technician must identify the intercepts. Match each type of intercept with the correct algebraic procedure used to find it.

A design technician is mapping a horizontal parabolic curve for a new architectural element. To find the $x$-intercept of the curve—the point where it crosses the horizontal axis—the technician must substitute the value ____ for the variable $y$ in the equation.
