Question

Find the axis of symmetry of the given function f(x) = 2x² - 4x + 7
Question 6 options:

1) x = 1

2) x = -5

3) x = 5

4) x = -1

Answer 1

use the formula for the x coordinate of the vertex; x_vertex = "h" =-b/(2a).

 

the axis of symmetry is the vertical line having equation x = h (this answer should be in the form of an equation).
