John was supposed to find the square root of a number. instead, he squared the number and said “625”. what number should tom have given?

which equals

which equals 5 so the number should have been 5

5

Step-by-step explanation:

If he squared a number and got 625, in order to undo that you will have to square root it.

So now back to the original question. If he was supposed to square root the actual number, which was 25, the answer would be 5 because

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

2.83941151 would be the answer you're looking for! : )
