Find the coordinates of the vertex for the parabola defined by the given quadratic function f(x)= x2 - 4x + 10.
Solution:
We have to find the coordinates of the vertex for the parabola.
For any equation of the type y = ax2 + bx + c, the vertex is given by (h,k)
Where, h = -b/2a and k = (4ac - b2)/4a.
Given, the equation is y = x2 - 4x + 10
Here, a = 1, b = -4 and c = 10
So, h = -(-4)/2(1)
h = 4/2
h = 2
4ac = 4(1)(10)
4ac = 40
So, k = [40 - (-4)2]/4(1)
k = (40 - 16)/4
k = 24/4
k = 6
Therefore, the coordinates of the vertex is (h,k) = (2, 6).
Find the coordinates of the vertex for the parabola defined by the given quadratic function f(x)= x2 - 4x + 10.
Summary:
The coordinates of the vertex for f(x) = x2 - 4x + 10 are (2, 6).
