Which of the following is the graph of f(x) = x2 − 5x + 4?

Functions f(x) and g(x) are shown below:f(x) = x2

In which direction and by how many units should f(x) be shifted to obtain g(x)?

Left by 4 units
Right by 4 units
Left by 8 units
Right by 8 units

Answers

Answer: The answer is (B) Right by 4 units.

Step-by-step explanation: The two functions f(x) and g(x) are defined as follows:

$f(x)=x^2,\n\ng(x)=x^2-8x+16.$

We are to check the correct transformation of the graph of f(x) to the graph of g(x).

We can rewrite the graph of g(x) as follows:

$g(x)=x^2-8x+16=x^2-2* x* 4+4^2=(x-4)^2.$

Comparing this with the equation of f(x), we can say that f(x) is shifted right by 4 units to obtain g(x).

The graphs of both the functions are shown in the attached figure.

Solve for 2 unknowns
3y + 3x =24
6y+3x = 39

Answers

The two unknown variable in the two given equations are "x" and "y".
3y + 3x = 24
Dividing both sides by 3 we get
y + x = 8
x = 8 - y
Putting the value of y in the second equation we get
6y + 3x = 39
Dividing both sides by 3 we get
2y + x = 13
2y + 8 - y = 13
y = 13 - 8
= 5
Putting the value of y in the first equation we get
y + x = 8
5 + x = 8
x = 8 - 5
x = 3
So the value of x is 3 and the value of y is 5. I hope the procedure is clear enough for you to understand.

Solve: 4y - 6 = 2y + 8

Answers

Answer:

y = 7

Step-by-step explanation:

Given

4y - 6 = 2y + 8 ( subtract 2y from both sides )

2y - 6 = 8 ( add 6 to both sides )

2y = 14 ( divide both sides by 2 )

y = 7
