In the point (x,y), x represents the domain of the function, and y represents the range of the function. A function is a part of a relation. In a relation, one domain can have multiple ranges. But in a function, one domain can not have multiple ranges. And in a function, multiple domains can have a range.

A function is a part of a relation. But a relation isn't always a function.
Function:
one domain only has a range, multiple domains can have one range

First option is not a function, it's a relation. Because one domain has multiple ranges ⇒ (0,3), (0,6)
Second option is a function! Because there's no multiple domains who have a range.
Third option is not a function, it's a relation. (1,4) and (1,6) is what makes it isn't a function.
Fourth option is not a function ⇒ (2,3), (2,6)

The answer is second option

Answer:

Step-by-step explanation:

Using the rule of exponents

$(a^nb^n)^{m}$ = $a^{(mn)}$ $b^{(mn)}$ , hence

( $a^{\frac{1}{2} }$ $b^{\frac{1}{3} }$ )^( $\frac{1}{2}$ )

= $a^{\frac{1}{2}(\frac{1}{2} ) }$ × $b^{\frac{1}{3}(\frac{1}{2}) }$

= $a^{\frac{1}{4} }$ $b^{\frac{1}{6} }$ → D

All real cube roots of 100/27

Nadya [2.5K]

4.64158883

−2.32079442+4.01973384i

−2.32079442−4.01973384i

100 is not a perfect cube so it will never have a whole root

The table represents a function.

Zarrin [17]

We have to complete the statement:

" The rate of change in the function y=x+4 is ______ the rate of change of the function represented in the table."

Let us consider the function represented in table.

The coordinates given in the table are:

(0,6) (2,8) (4,10) and (6,12)

Consider the first two coordinates (0,6) and (2,8)

$x_{1}=0 , y_{1}=6, x_{2}=2 , y_{2}=8$

Equation of line is given by $(y-y_{1})=m(x-x_{1})$

where 'm' is slope(rate of change) is given by the formula:

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

So, $m = \frac{8-6}{2-0}=1$

So, equation of line is :

(y-6)= 1 (x-0)

y-6=x

y=x+6

Comparing it with standard equation of line y=mx+c with slope 'm'.

So, we get m(Rate of change)=1.

Now,

We will find the rate of change(slope) in the function y=x+4

Comparing it with standard equation of line y=mx+c with slope 'm'.

So, we get m(Rate of change)=1.

So, " The rate of change in the function y=x+4 is equal to the rate of change of the function represented in the table.

What do these questions mean?? relations part two only btw

loris [4]

I'll do problem 1 to get you started.

========================================

1a. Pick any four ordered pairs of the form (x,y) such that y = 2x. In other words, these points are all on the line y = 2x.

Four such points are: (1,2), (2,4), (3,6) and (4,8)

There are infinitely many points to pick from.

========================================

1b. Similar to the first problem, but now y = x+5. Whatever the x coordinate is, we add 5 to it to get the y coordinate.

Four such points are: (0,5), (1,6), (2,7), (3,8)

There are infinitely many points

========================================

1c. Similar idea as before, but now y = x-4

Four points on this line are: (0,-4), (1,-3), (2,-2), (3,-1)

There are infinitely many points.

=======================================

1d. Take half of the x coordinate to get the y coordinate. The equation is y = x/2 or y = (1/2)x or y = 0.5x

Four points on this line are: (2,1), (4,2), (6,3), (8,4)

There are infinitely many points.
