Given g of x equals cube root of the quantity x plus 6, on what interval is the function negative?
nikdorinn [45]

The interval for the function to be negative will be (-∞<x<-7).

<h3>What is a function?</h3>

A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

Here we have a function:-

g(x) = ∛(x+6)

If we put the value of x lesser than 6 in the function we will always get a negative value so the interval will be:-

(-∞<x<-7).

Therefore interval for the function to be negative will be (-∞<x<-7).

Can someone please help me I have been stuck what one
Viefleur [7K]

Answer:

The inequality matches the graph is 2n + 5 ≤ 7 ⇒ A

Step-by-step explanation:

Let us solve the question

<em>From the given graph</em>

∵ The arrow starts from 1 and pointed to the left (negative part)

∵ The starting point of the arrow is bold

∴ The sign of the inequality is ≤ (smaller than or equal)

→ That means the solution of the inequality is all the numbers ≤ 1

∴ The solution of the inequality is n ≤ 1

→ Look at the choices and find which one has the sign ≤ and check if

  it will give the same solution or not

∵ The inequality is 2n + 5 ≤ 7

→ Subtract 5 from both sides

∴ 2n + 5 - 5 ≤ 7 - 5

∴ 2n ≤ 2

→ Divide both sides by 2

∴ n ≤ 1

∵ The inequality gives the same solution of the given graph

∴ The inequality matches the graph is 2n + 5 ≤ 7
