Which relation represents a function?

Mathematics

Airida [17]3 years ago

<h3>Answer: Choice C</h3><h3>{ (-2,2), (0,2), (7,2), (11,2) }</h3>

Here we don't have any repeated x values.

In choice A, x = 2 repeats. In other words, x = 2 leads to multiple y outputs. So this is not a function. Choices B and D are similar stories. A function is only possible if every x leads to exactly one y value only. The graph must pass the vertical line test.

Side note: the y values can repeat, but the function won't be one-to-one.

An angelfish was 1 1/2 inches long when it was bought. Now it is 2 1/3 inches long.
____ [38]

A)

Earlier, The length of the angelfish  = 1 \frac{1}{2} inches

Now, the length of angelfish = 2 \frac{1}{3} inches

We have to determine the grown length of angelfish

=  2 \frac{1}{3} -  1 \frac{1}{2}

= \frac{7}{3}- \frac{3}{2}

LCM of '2' and '3' is '6',

= \frac{14-9}{6}

= \frac{5}{6} inch

Therefore, the angelfish has grown by \frac{5}{6} inch.

B)

We have to determine the increased length of angelfish in feet.

Since 1 inch = \frac{1}{12} foot

So, \frac{5}{6} inch = \frac{5}{6} \times \frac{1}{12} = \frac{5}{72}

= 0.069 foot.

D+7/−3=4<br> What is d?<br> Thanks!
givi [52]

Answer

\boxed {d= \frac{19}{3}}


Solution

Simplify both sides of the equation.


\frac{7}{3} + \frac{-7}{3}


We are left with d = 4+\frac{7}{3}


Add

\frac{12}{3}+\frac{7}{3} =\frac{19}{3}


Hence, d = \frac{19}{3}
