Since the temperature starts at 40 degrees F at sunrise and increases 4 degrees every hour afterward, we can begin our equation.
If you visualize the graph, the y-axis (left side) will denote the degrees and increase slightly every hour. The x-axis (at bottom) will show the hours as they pass by. In slope-intercept form, the b must be 40 degrees, since this is where we start, and the slope m must be 4, since this is the amount the temperature is changing every hour.
Therefore y=4x+40
This equation will tell you the temperature (y) at any hour (x).
jus go on the other side of the graph.

Answer:To find the x-intercept, substitute in 00 for yy and solve for xx. .
x-intercept(s): (1,0),(−4,0)(1,0),(-4,0)
y-intercept(s): (0,−4)
Step-by-step explanation:Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: (−3/2,−25/4)(-3/2,-25/4)
Focus: (−3/2,−6)(-3/2,-6)
Axis of Symmetry: x=−3/2 x=-32
Directrix: y=−13/2 y=40−3−4−32−254−1−60−4
