Question

Please help me and explain.

Answer 1

Answer:

Step-by-step explanation:

In the set [-5, 3], only A fits in. B is pi, which has a value of 3.1415....which is outside of the interval since it's greater than 3. C. is -6 which is less than -5, so that's outside of the interval as well. D is the square root of 36 which is 6...outside of the interval again. A it is.  A could be rewritten as

$-\frac{1}{2^2} =-\frac{1}{4}$
