given the equation Y equals one the square root of one minus acts, and we're gonna find the value of this function at input. Negative three. So squared of one minus negative, 31 minus negative. Three is like one plus three. And we know that one plus three is four. And we also know that Square four is to probably showed way more steps than I needed to. It's a mental math we could have done there, but the answers to
