What is Domain and Range of the graph
Katena32 [7]

Answer:

Use the vertical line testing, which means that if the line touches one point then it is a function. If it touches more than 1 point, then it is not a function. Also, if one x value leads to one y-value then it is a function. If different x-values lead to one y-value it is also a function.

Factor completely 3ab − 5ax + 9b − 15x.
Alik [6]

Answer:  The answers are given below.

Step-by-step explanation:  We are given to factorise some quadratic expressions.

We will be using the following factorisation formula:

x^2+ax+bx+ab=(x+a)(x+b).

The factorisation is as follows:

We have

(1)~3ab-5ax+9b-15x\\\\=a(3b-5x)+3(3b-5x)\\\\=(3b-5x)(a+3).

Thus, option (B) (3b-5x)(a+3) is correct.

(2)~5x(x+3)+6(x+3)\\\\=(x+3)(5x+6).

Thus, option (B) (x+3)(5x+6) is correct.

(3)~2cb+7cx+2b+7x\\\\=c(2b+7x)+1(2b+7x)\\\\=(2b+7x)(c+1).

Thus, option (B) (2b+7x)(c+1) is correct

(4)~21x^3+35x^2+9x+15\\\\=7x^2(3x+5)+3(3x+5)\\\\=(3x+5)(7x^2+3).

Thus, option (D) (3x+5)(7x^2+3) is correct.

(5)~9xy+36x-10y-40\\\\=9x(y+4)-10(y+4)=(y+4)(9x-10).

Thus, option (C) (y+4)(9x-10) is the correct option.

(6)~14bx^2-7x^3-4b+2x\\\\=7x^2(2b-x)-2(2b-x)\\\\=(2b-x)(7x^2-2).

Thus, option (B) (2b-x)(7x^2-2) is the correct option.

(7)~4xy+9x+24y+54\\\\=x(4y+9)+6(4y+9)\\\\=(4y+9)(x+6).

Thus, option (D) (4y+9)(x+6)  is correct.
