What is the parent function for the following<br><br> f(x) = (x-2) (x-1)
Taya2010 [7]

Answer:

The parent function of  f(x) = (x-2) (x-1) is  P(x) = x^2- 3 x + 2.

Step-by-step explanation:

Here, f(x) = (x-2) (x-1)

Now, parent function of a given function is the function, which is PRODUCT OF ALL IT S FACTORS.

Now, here, f(x) has two factors ( x- 2) and ( x-1)

So, the parent function p(x) of f(x) is given as the product of both the factors.

So, we get:

P(x)  = (x-2) (x-1) \\=  x( x-1) -2(x-1)\\=x^2 - x -2x + 2\\= x^2- 3 x + 2\\\implies P(x) = x^2- 3 x + 2

Hence, here the parent function of  f(x) = (x-2) (x-1) is  P(x) = x^2- 3 x + 2.

5x-0.1=4x I need to know what X is not sure how to solve
masha68 [24]
<span>5x-0.1=4x
Subtract 5x from both sides so that the x variable is only on one side
-0.1=-x
Divide both sides by -1 to get rid of the negative on the side with the x variable
Final Answer: 0.1=x</span>

Three sets have 5, 10, 15 elements, respectively. How many elements can their union and intersection have?​
Degger [83]

Answer:

Union = 15

Step-by-step explanation:

Given

n(A) = 5; n(B) = 10; n(C) = 15

Solving (a): Possible union elements

This is the represented by element with the largest number of the sets

i.e.

Union = 15

Solving (b): Possible intersection elements

This is the represented by element with the least number of the sets

i.e.

Intersection = 5

Jerry is saving money for a job. After the first 3 weeks he saved $135. Assuming the situation is proportional. Use the unit Rae
VMariaS [17]

The equation would be s = 45w and she would have 360 in 8 weeks.

In order to find this, we first have to find the per week amount. To find this, we divide the amount by the number of weeks.

135/3 = 45

Now that we have this we can multiply that by the variable and set equal to the total amount.

s = 45w

Now to find the amount in 8 weeks, simply plug in the 8 to w.

s = 45w

s = 45(8)

s = 360

In order, list each property used to find the equivalent expression for 8 + 4(2x - 6). Step 1: 8 + 8x - 24 Step 2: 8 - 24 + 8x S
amid [387]
1. distributive property
2. commutative property (the order of 8x and -24 is swapped)
3. reflexive property ((8-24) = -16; -16 is substituted for 8-24. I prefer "substitution property".)
4. commutative property (the order of 8x and -16 is swapped)
5. distributive property
