Graph the function y = 4x4 – 8x2 + 4. Which lists all of the turning points of the graph? (0, 4)
(–1, 0) and (1, 0)
(–1, 0), (0, 4), and (1, 0)
(–4, 0), (–1, 0), (0, 4), and (1, 0)

Step-by-step explanation:

First we should solve this equation given for 'y'

y=4*4-8*2+4

y=16-16+4

y=4

Now we have value of 'y' we can fnd which points have y coordinate with value of 'y'.i.e., 4

(0,4) (-1,0) will be the answer
