I NEED HELP ASAP First, find the increasing functions. Then, classify each increasing function as having a larger or a smaller u
aev [14]

Answer:

In descending order the function are represented as D>F>A>B>E>C

Step-by-step explanation:

Whether it is increasing or is the larger or smaller number it all depends on its slope.

Equation of line y=m(x)+c,and m is the slope.

So we will work with the slopes of each equations and arrange them in descending order.[Greater to larger number sequence]

Slopes are \frac{4}{3}, \frac{5}{4}, \frac{-2}{1},\frac{7}{4}, \frac{6}{5}, \frac{8}{5}

We will equate the denominator by taking LCD of it then multiply numerator and denominator with a fix number which can bring all the denominator same.

LCD of the denominator (1,3,4,5)=60

Example:

\frac{4}{3}=\frac{4\times 20}{3\times 20}= \frac{80}{60}

Similarly we will equate all the fractions.

So the slope are \frac{80}{60}, \frac{75}{60}, \frac{-120}{60},\frac{105}{60}, \frac{72}{60}, \frac{96}{60}

In descending order the numbers are:

\frac{105}{60},\frac{96}{60}, \frac{80}{60}, \frac{75}{60},\frac{72}{60},\frac{-120}{60}

According to the option the right choice are as follows:

D>F>A>B>E>C
