Ryker is given the graph of the function \( y = \frac{1}{2}x^2 - 4 \). He wants to find the zeros of the function but is unable to read them exactly from the graph. Find the zeros and give the answer to the nearest tenth.

y = 2 1 ​ x 2 − 4 zeros w h e n y = 0 2 1 ​ x 2 − 4 = 0 2 1 ​ x 2 = 4 / ⋅ 2 x 2 = 8 x = − 8 ​ an d x = 8 ​ x ≈ − 2.8 an d x ≈ 2.8 ​ ​
