Identify the function as either a constant, direct variation, absolute value or greatest integer function f (x)=-4
boyakko [2]
Answer: Constant

No matter what the input x is, the output f(x) is going to be -4. Therefore, the output is constant. 

Note: f(x) can be interchanged with y. So we can say y = -4.

Which relation is a function?
IceJOKER [234]

Answer:

The bottom right option

Step-by-step explanation:

Functions need each input to map to exactly one output. Graphically speaking, this means that any two points on the function cannot have the same x-coordinate.

Given this, the bottom right option is the only one that fits these circumstances.

Solve the equation. Then check your solution
kondaur [170]

Answer:

  • Option <u>B </u>is correct i.e. <u>2</u><u>1</u>

Step-by-step explanation:

In the question we're provided with an equation that is :

  • v/7 = 3

And we are asked to find the solution for the equation .

<u>Solution</u><u> </u><u>:</u><u> </u><u>-</u>

<u>\longrightarrow \:  \frac{v}{7}  = 3</u>

Multiplying by 7 on both sides :

\longrightarrow \: \frac{v}{ \cancel{7} }\times  \cancel{7}  = 3 \times 7

On further calculations , we get :

\longrightarrow \:  \blue{\boxed{v = 21}}

  • <u>Therefore</u><u> </u><u>,</u><u> </u><u>solution</u><u> </u><u>for</u><u> equation</u><u> </u><u>is </u><u>2</u><u>1</u><u> </u><u>.</u><u>That </u><u>means</u><u> </u><u>option </u><u>B </u><u>is </u><u>the </u><u>correct</u><u> answer</u><u>.</u>

<u>Verifying</u><u> </u><u>:</u>

We are verifying our answer by substituting value of v in the equation given in question :

\longrightarrow \: \frac{v}{7}  = 3

Putting value of v :

\longrightarrow \:  \cancel{\frac{21}{7}}  = 3

By dividing 21 with 7 , we get :

\longrightarrow \:3 = 3

\longrightarrow \: L.H.S=R.H.S

\longrightarrow \: Hence , \: Verified.

  • <u>Therefore</u><u> </u><u>,</u><u> </u><u>our </u><u>answer</u><u> is</u><u> valid</u><u> </u><u>.</u>
