Find the domain and range of 1/t+2

kotegsom [21]

Answer:

Domain = (-∞, -2) ∪ (-2, ∞).

Range = (-∞, 0) ∪ (0, ∞).

Step-by-step explanation:

t can't have the value -2 because that would make 1/(t + 2) = 1/0 which is undefined.

So the domain is All real values of t. except t = -2.

As t approaches infinity or negative infinity f(t) approaches zero, and as t approaches -2 from below or above f(t) approaches negative infinity or positive infinity.

vesna_86 [32]

Answer:

110 students

Step-by-step explanation:

The number of students who have only taken calculus is given by the number of students who have taken calculus minus the students who have taken both classes:

$C =100 -50\\C= 50\ students$

The number of students who have only taken discrete mathematics given by the number of students who have taken discrete mathematics minus the students who have taken both classes:

$D =110 -50\\C= 60\ students$

The number of students that have taken a course in either calculus or discrete mathematics is:

$E = C+D = 50+60\\E= 110\ students$

Which list represents the independent values on this graph? 0, 100, 250, 200, 300, 350, 400, 500, 650, 700, 750 1, 2, 3, 4, 5, 6

worty [1.4K]

A scatter plot is used to relate the dependent and the independent values

The list of independent values is:1, 2,3, 4,5,6,7,8,9,10

<h3>How to determine the independent values</h3>

The ordered pairs on the scatter plot are:

(x,y) = (1, 100), (2,250) , (3,200) , (4,300), (5,400), (6,350), (7,500) , (8,650) , (9,700) and (10,750).

Remove the y values

x = 1, 2,3, 4,5,6,7,8,9,10

The x values represent the independent values

Hence, the list of independent values is:1, 2,3, 4,5,6,7,8,9,10
