Hector and Linh are working individually on a problem involving the function f(x)=x2−5. On a domain where f is invertible, Hector says that f−1(4)=3, and Linh says that f−1(4)=−3.

Is Hector correct? Is Linh correct? Justify your answer.

Th perimeter of a rectangular garden is 150 feet. the length is 50 feet longer than the width, w. which equation could be used to calculate the width of the garden? a.) 2w+ 2(w-50) =150 b.) 2w+50 + 2w =150 c.) 2(w+50) + w =150 d.) 2w+ 2(w + 50) = 150 need asap. will give brainliest !
