Help asap, please! Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 19 units below the vertex of the graph of g(x).

Which pair of functions could have been used to create the graphs of g(x) and h(x)?

h(x)=x2−19 and g(x)=x2

h(x)=(x−19)2 and g(x)=x2

h(x)=x2+19 and g(x)=x2

h(x)=(x+19)2 and g(x)=x2

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
