Question

y=(x−5)2−4
Identify the vertex, equation for the axis of symmetry, domain, range and x- and y-intercepts of the parabola.


y=−2(x+8)2+2
Identify the vertex, equation for the axis of symmetry, domain, range and x- and y-intercepts of the parabola.

Answer 1

y=(x−5)2−4
y+4 = (x−5)2
vertex (5,-4)

Answer 2

vertex = -b/2a
domain is = x
range = y
x intercept is when y is = 0
y intercept is when x is = 0
