Hello there!

Today we are just working with dividing functions.

f(x)=4x+1 and g(x)=x²-5 and we want to find (g/f)(x).

just take the expression given by g(x) and put it over the expression given by f(x).
x²-5/4x+1 is the answer, BUT, a more explicit answer is c because it also states what x CANNOT be.

This is why x²-5/4x+1, x cannot equal -1/4 is the answer. This is simply because you can't divide by zero and by setting the denominator equal to 0, you can figure out what x can't be.

This means that c is the answer!

I really hope this helps!
Best wishes :)

Virty [35]

Answer:

<h2>48 600 yd²</h2>

Step-by-step explanation:

If a shape is scaled by a certain scale factor then :

<u><em>the area of the new shape</em></u> =  (<em>the scale factor</em>) times (<em>the area of the original object</em>)

………………………

the new recreation complex was created by enlarging the old community soccer field by a scale factor of 9

Then

The area of the new recreation complex = 9² × 600 = 81×600 = 48 600 yd²

Find the domain of y=2/3x-1 if the range is {-3, -1, 7, 17}.
White raven [17]
<h3>Answer: The domain is {-3, 0, 12, 27}</h3>

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

Explanation:

First solve for x to get

y = (2/3)x - 1

y+1 = (2/3)x

(2/3)x = y+1

x = (3/2)*(y+1)

-------

Now plug the values given into y. Do so one at a time. Lets plug in y = -3

x = (3/2)*(y+1)

x = (3/2)*(-3+1)

x = 1.5*(-2)

x = -3

So the domain value x = -3 corresponds to the range value y = -3.

-------

Repeat for y = -1

x = (3/2)*(y+1)

x = (3/2)*(-1+1)

x = 1.5*0

x = 0

The domain value x = 0 corresponds to the range value y = -1

-------

Repeat for y = 7

x = (3/2)*(y+1)

x = (3/2)*(7+1)

x = 1.5*8

x = 12

The domain value x = 12 corresponds to the range value y = 7

-------

Repeat for y = 17

x = (3/2)*(y+1)

x = (3/2)*(17+1)

x = 1.5*18

x = 27

The domain value x = 27 corresponds to the range value y = 17
