What is the domain of the function y=in(x+2) x<-2 x>-2 x<2 x> x<-2 x>-2 x<2 x>2
aev [14]

For this case we must find the domain of the following function:

y = ln (x + 2)

By definition, the domain of a function is given by all the values for which the function is defined.

In this case, the argument of the expression must be greater than 0 to be defined.

x + 2> 0\\x> -2

Thus, the domain of the function is given by all the values of x greater than -2.

Answer:

Domain: x> -2

Part A: Write an algebraic expression for 6 more than 7 times a number. (5 points)
m_a_m_a [10]

The algebraic expression of the part A is 6+7x. And the verbal expression for 3*(n+8) is "the triple of the sum between the numbers n and 8".

<h3>Linear Expression</h3>

A linear expression can be represented by a line. The standard form for this equation is: y=ax+b , for example, y=2x+7.

  • Part A

First, you should choose a variable for unknow number. Here, the variable will be x. Then, 7 times a number can be represented for 7x.

The word <em>more </em>will be represented for the add symbol (+). Thus,

the algebraic expression is 6+7x.

  • Part B

The expression 3*(n+8) can be represented for the sentence:

The triple of the sum between the numbers n and 8.
