Determine the equation of a cubic function with zeros at -2, -4, and 3 that passes through the point (4, 144)​
levacccp [35]

\boxed{f(x)=3(x+2)(x+4)(x-3)}

<h2>Explanation:</h2>

Since the cubic function has zeroes at:

x=-2 \\ \\ x=-4 \\ \\ x=3

Then, we can write this function as:

f(x)=a(x-(-2))(x-(-4))(x-3) \\ \\ f(x)=a(x+2)(x+4)(x-3)

So our goal is to find the leading coefficient a. Since that cubic function passes through the point (4, 144), then it is true that:

f(4)=144 \\ \\ \\ So,\ plug \ these \values \ in \ the \ function: \\ \\  f(x)=a(x+2)(x+4)(x-3) \\ \\ 144=a(4+2)(4+4)(4-3) \\ \\ 144=a(6)(8)(1) \\ \\ 144=a(48) \\ \\ a=\frac{144}{48}=3

Finally, the cubic function is:

f(x)=3(x+2)(x+4)(x-3)

The graph is shown below. As you can see the zeroes are:

(-2,0) \\ \\ (-4,0) \\ \\ (3,0)

And the function passes through (4,144)

Order the numbers from least to greatest. Put the lowest number on the left. 11/12 , 9/8 , 1/3 ,
UkoKoshka [18]

Answer:

1/3,11/12,9/8

Step-by-step explanation:

Hi! Let's start off with creating common denominators for all three of these fractions.

The LCM (least common multiple) of these three denominators is 24, which means that the three numbers you see at the bottom of the fraction (12, 8, and 3) all in some way have a number that will cause it to multiply to 24, and will make it much more easier to determine the fraction.

1) Change all of the denominators into 24 by multiplying the right number

11/12×2/2=>22/24

9/8×3/3=>27/24

1/3×8/8=>8/24

So now I want you to imagine that the denominators don't exist. From there, you can sort out the fractions from least to greatest! Hope you understood this :)
