Find domains of the following expressions.
sqrt(2-3x)+sqrt(5-x)

(-∞ , 2/3)

Step-by-step explanation:

To find the domain of a radical , we will set the function inside the radical greater than or equal to zero , that is

2 - 3x ≥ 0

2  ≥ 3x

2/3  ≥ x

that is : x ≤ 2/3

Also

5 - x  ≥ 0

5  ≥ x

That is : x ≤ 5

Therefore , the domain of the expression  is  x ≤ 2/3 and  x ≤ 5

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
