What is the range of the function (e^x)/(e^x)+c? Assume that c is a constant greater than zero.

mr_godi [17]

Try this explanation:
1. if to re-write the given function as:
$y= \frac{e^x}{e^x+C}; \ \ \textless \ =\ \textgreater \ \ y=1- \frac{C}{e^x+C};$
then it is possible to define its range:
2)
$\lim_{x \to+ \infty}[1- \frac{C}{e^x+C}]=1; \\ \lim_{x \to- \infty}[1- \frac{C}{e^x+C}]=0$

answer: (0;1)

MP Persevere with Problems Suppose 20

grigory [225]

9514 1404 393

Answer:

8 people

Step-by-step explanation:

If 20 of 140 people play tennis, then in a group of 504 people, we expect ...

(20/140) × 504 = 72 . . . . tennis players

If 1 of 9 tennis players has a coach, then in a group of 72 tennis players, we expect ...

(1/9) × 72 = 8 . . . . have a coach

We expect 8 of the 504 people have a tennis coach. We made this prediction by applying the given rates to the larger group.

Slope = -8, passing through (2,5)

Marrrta [24]

Y - y₁ = m(x - x₁)
y - 5 = -8(x - 2)
y - 5 = -8(x) + 8(2)
y - 5 = -8x + 16
<u> + 5 + 5</u>
y = -8x + 21

How to sovle <br> (x+1/x)^2

Slav-nsk [51]

$(\frac{x + 1}{x} ) ^{2} \\ = \frac{ {(x + 1)}^{2} }{ {x}^{2} } \\ = \frac{ (x + 1)(x + 1) }{ {x}^{2} } \\ = \frac{ {x}^{2} + 2x + 1}{ {x}^{2} }$

Hope you could get an idea from here.

Doubt clarification- use comment section.
