Vertex/Axis of Symmetry for x^2+2x=35
Vertex/Axis of Symmetry for x^2+2x=35
Find the vertex, vertex form, and axis of symmetry forx^2+2x=35
The quadratic you entered is not in standard form: ax2 + bx + c = 0
Subtract 35 from both sides
x2+2x - 35 = 35 - 35x2+2x - 35 = 0
We have our a, b, and c values:
a = 1, b = 2, c = -35
Find the vertex, vertex form, and axis of symmetry of the quadratic
x2 + 2x - 35=
Vertex of a parabola
(h,k) where y = a(x - h)2 + kUse the formula rule.Our equation coefficients are a = 1, b = 2
The formula rule determines h
h = Axis of Symmetryh = | -b |
2a |
Plug in -b = -2 and a = 1
h = | -(2) |
2(1) |
h = | -2 |
2 |
h = -1 ← Axis of Symmetry
Calculate k
k = ƒ(h) where h = -1ƒ(h) = (h)2(h)35=
ƒ(-1) = (-1)2(-1)35=
ƒ(-1) = 1 - 2 - 35
ƒ(-1) = -36
Our vertex (h,k) = (-1,-36)
Determine our vertex form:
The vertex form is: a(x - h)2 + kVertex form = (x + 1)2 - 36
h = -1
vertex (h,k) = (-1,-36)
Vertex form = (x + 1)2 - 36
What is the Answer?
h = -1
vertex (h,k) = (-1,-36)
Vertex form = (x + 1)2 - 36
