The product of two numbers is 44. find the sum of the two numbers s(x) as a function of one of the numbers, x. s(x)

1 answer:

3 0

Call the numbers x and y. According to the first sentence, xy = 44. You can rearrange to solve for y: y = 44/x. The sum of the numbers, s(x), is x + y, but we just found a way of expressing y in terms of x. Therefore: the sum expressed as a function of one of the numbers (x) is:

s(x) = x + 44/x

Which is the graph of the function f(x)= negative square root x

Vsevolod [243]

First, note that $\sqrt{x}$ is always positive (except for x=0), so $-\sqrt{x}$ must be always negative.

Thus, the only plausible graphs are 1 and 3 since they are below the x-axis.

Now, $\sqrt{x}$ and $-\sqrt{x}$ are only defined for x≥0, because only for these x'es we can take the square root.

Note that the third graph has domain (-infinity, 0], so it is not the right one, while 1 is ok.

Answer: first graph
