Graph y-3=(x+2)^2
Problem
Solution
Identify the form of the equation. The equation
y−3=(x+2)2 is a parabola in vertex form, which is generally written asy−k=a*(x−h)2 Determine the vertex
(h,k) By comparingy−3=(x+2)2 to the standard form, we findh=−2 andk=3 The vertex is(−2,3) Identify the direction of opening. Since the coefficient
a=1 is positive, the parabola opens upward.Find the y-intercept by setting
x=0
The y-intercept is
Find additional points using symmetry. Since the axis of symmetry is
x=−2 the point symmetric to(0,7) is(−4,7) Sketch the graph by plotting the vertex
(−2,3) the y-intercept(0,7) and the symmetric point(−4,7) then drawing a smooth U-shaped curve through them.
