HELP ); Match each function formula with the corresponding transformation of the parent function y = - (x + 2)2.

1. y = - (x + 4)2
2. y = - (x + 2)2 - 2
3. y = (x - 2)2
4. y = 2 - (x + 2)2
5. y = -x2
6. y = (x + 2)2

A. Reflected across the x-axis and the y-axis

B. Translated right by 2 units

C. Translated up by 2 units

D. Reflected across the x-axis

E. Translated left by 2 units

F. Translated down by 2 units

Answers

Answer 1
Answer:

Always remember general rules of transformation.

1) Vertical Shift:

y= f(x)+k ; shifts the graph of f up k units if k>0, shifts it down |k| units if k<0.

2) Horizontal Shift:

y=f(x+h) ; shifts the graph of f left h units if h>0, shifts it right |h| units if h<0.

3) Reflection across x-axis

y= - f(x) ; reflect the graph of f across the x-axis.

Now,

The parent function is y= -(x+2)²

1. y= -(x+4)²

In this question +2 is added with x+2 and becomes y= -(x+2+2)²=-(x+4)²

So, according to rule 2 it will shift the parent function to the left by 2 units.

E is the correct option.

2. y = - (x + 2)² - 2

In this question, -2 is added to the parent function and we get y= - (x + 2)² - 2

So, according to rule 1, it will shift the graph down by 2 units.

F is the correct option.

3. y=(x - 2)²

In this question, two operations are performed on the parent function.

First one, -4 is added with x+2 so we get x+2-4= x-2

Second one, -1 is multiplied with parent function.

By performing the two operations at a time we get a new function which is

y=-(-(x+2-4)²)=(x-2)²

The first operation will translate the parent function 4 units right (according to rule 2).

The second operation will reflect the graph across x-axis(according to rule 3).

D and translation 4 units to right is correct option.

4. y= 2 -(x+2)²

In this question, we add +2 to the parent function so according to rule 1 it will shift the graph up by 2 units.

C is the correct option.

5. y= -x²

In this question, we add -2 to x+2 so we get a new function y= -(x+2-2)²=-x²

So, according to rule 2 it will shift the graph right by 2 units.

B is the correct option.

6. y= (x+2)²

In this question, -1 is multiplied with parent function and we get

y= -(-(x+2)²)= (x+2)²

So, according to rule 3 , graph is reflected across x-axis.

D is the correct answer.

The graph of parent function and question no. 1,2,3 are attached separately, while question no. 4,5,6 are attached in combined form(due to space limit).

Oh that's easy, all you have to do is use the quadratic equation :)

A bank offers a 3.7% annual interest rate for a retirement savings account. A worker puts $8,000 into the account. How much will be in the account after a year?

Answers

Answer:

$8,296

Step-by-step explanation:

(see attached for reference)

assuming simple interest, the final amount is given by

A = P(1 + rt), where

A = final amount (we are asked to find this)

P = principal amount = given as $8000

r = rate = 3.7% = 0.037

t = time = 1 year

substituting the known values into the formula,

A = P(1 + rt)

= 8,000 [ 1 + (0.037)(1) ]

= $8,296

What is '7b-2b+3-1' ? Need working and it's equations!!

Answers

7b - 2b + 3 - 1 = 0

(7b - 2b) = 5b
3 - 1 = 2

Thus:

5b + 2 = 0
5b = -2
b = -2/5 = -0.4
7b-2b+3-1=0
5b+2=0
5b=-2
b=-2/5
