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.

72 inches=___ yards please and thank you for your help
I am Lyosha [343]

We know that:

1yd=36in\text{.}

Then:

1in=\frac{1}{36}yd\text{.}

Therefore:

72in=72\cdot(\frac{1}{36}yd)\text{.}

Simplifying the above result we get:

72\cdot\frac{1}{36}yd=2yd\text{.}

Answer:

72\text{inches}=2\text{yards.}
