Question

Ryker is given the graph of the function y= 1/2x^2 - 4 . He wants to find the zeros of the function but is unable to read them exactly from the graph. find the zero in simplest radicle form

Answer 1

`y = (1)/(2x^(2) - 4)`

`0 = (1)/(2x^(2) - 4)`

`0(2x^(2) - 4) = (2x - 4)((1)/(2x^(2) - 4))`

`0(2x^(2)) - 0(4) = 1`

`0 - 0 = 1`

`0\\eq1`
