The table shows the input and output of a function Table(input:3,4,6,11. Output:5,7,11,21) (a) Explain what makes this set of da
JulijaS [17]

Ans(a):

We know that a function can't have repeated x-values.

In given table we see that there i no repeating x-value. That's why the given table  represents function.


Ans(b):

We know that a function can't have repeated x-values.

So if in given table we see any repeating x-value then that may cause the given data set to not be a function.

like if we have 3, 4, 3, 11 in the input then it will not be a function.


Ans(c):

we can use two points say (3,5) and (4,7) to find the linear equation of the form y=mx+b

slope is given by

m=\frac{y_2-y_1}{x_2-x_1}=\frac{7-5}{4-3}=2

Noow plug value of m=2 and any point say (3,5) into y=mx+b

5=2(3)+b

5=6+b

-1=b

now plug m=2 and b=-1 in y=mx+b, we get y=2x-1

Hence required equation in function notation can be written as

f(x)=2x-1.


Now to prove that above function is correct, we just graph the given points from table and the obtained function.

We see that points lie on the grpah of f(x)=2x-1.

Which proves that our equation is correct.

Answer:

A

Step-by-step explanation:

<h3>Numerator</h3>

(3x)(3x) = 9x^2

√9x^2 = 3x

Numerator = 3x

<h3>Denominator</h3>

√18y^2 = √18 · √y^2

√18 = 3√2

√y^2 = y

3√2y

Denominator = 3√2y

Now we need to rationalize the denominator, and get rid of the square root on the bottom

\frac{3x}{3\sqrt{2} y} * \frac{3\sqrt{2} }{3\sqrt{2}} = \frac{6x\sqrt{2} }{12y} = \frac{x\sqrt{2} }{2y}

The value y of varies directly with x. When y = 19.375, x = 7.75.
Bingel [31]

Answer: (X,Y) = (0.4, 7.75)

Step-by-step explanation:

Y=7.75,

19.375X=7.75

Then solve for X

Divide 19.375 on both sides to get X=0.4

Y=7.75

X=0.4
