Sketch the asymptotes, and graph the function. y = 5/x-2+3

Mathematics
2 answers:
Digiron [165]3 years ago

Y=5/(x-2)+3

Vertical Asymptote:
x-2=0
Solving for x:
x-2+2=0+2
x=2

Horizontal Asymptote:
Lim x→-Infinite y = Lim x→-Infinite 5/(x-2)+3=5/(-Infinite-2)+3=5/(-Infinite)+3
Lim x→-Infinite y = 0+3→Lim x→-Infinite y = 3

Lim x→Infinite y = Lim x→Infinite 5/(x-2)+3=5/(Infinite-2)+3=5/(Infinite)+3
Lim x→Infinite y = 0+3→Lim x→Infinite y = 3

Horizontal Asymptote: y=3

Please, see the graph in the attached file.
Thanks.

The figure attached shows the graph of the function with the two asympotes.
The formulae of those asympotes are:
y = 3, and x = 2.

This is how you work to find them.

1) The function will have vertical asympotes where the limit grows indefinetly (approach +/- ∞).

2) That happens for x = 2, where the function is not defined but it grows indefinetly toward infinity (if you come from the right side) or toward negative infinity (if you come from the left side). So, the vertical asymptote is the line x = 2.

3) The function will have a horizontal asymptote if the function tends to a constant value as x approaches infinity or negative infinity.

4) In this case, you find that the limit of the function when x appraches - ∞ or +∞ is 3.


That results in one horizontal asymptote which is y = 3.

Each student at some college has a mathematics requirement M (to take at least one mathematics course) and a science requirement
Furkat [3]

all students = 150

M = 60

S = 45

M and S = 25

(a) At least one of the two requirements:

M or S = M + S - (M and S) = 60 + 45 - 25 = 80

(b) Exactly one of the two requirements:

(M or S) - (M and S) = 80 - 25 = 55

(c) Neither requirement:

(all students) - (M or S) = 150 - 80 = 70

Pls help!!! Will give brainliest answer to whoever answeres first and correctly
joja [24]

16) 164 * .25 = 41  

D. 164

17) 26.80 * .15 = 4.02

C. $4.05

18) 70 * .2 = 14

70 * .08 = 5.6

14 + 5.6 + 70 = 89.6

C. $89.6

How do you put 12 over 60 in a simplest form
stich3 [128]
That would be 1/5 in simplest form you can divide both numbers by 12 and when you do you get 1/5. Hope this helps!

How many terms are in the arithmetic sequence 5, 1, −3, . . . , −111?
masya89 [10]
Here, it helps to find a general expression for the nth term in the sequence. Since the sequence is arithmetic, the general term is a_n = a + bn, where b is the common difference. By inspection of the first few terms we see the common difference is -4. Then by solving a_1 = a - 4x1 = 5, we obtain a = 9, so the nth term is: a_n = 9-4n. We then solve a_n=-111 for n, so 9-4n=-111. Rearranging, we get 4n=9+111, or 4n=120, or n=30. Thus there are 30 terms in the sequence.
