Determine the axis of symmetry and the vertex of the given function. y = 2x2 − 12x + 21 Axis of symmetry:

Equation of the axis of symmetry is:   x = 3

Step-by-step explanation:

The equation

is the equation of a parabola, of the form

   whose vertex is located at the x-coordinate:

Then, for our case the x position of the given parabola, is:

Then the equation of the axis of symmetry, which is a vertical line that goes through the vertex, would be given by:

x = 3

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
