Given the function f(x) = x2 and k = –3, which of the following represents a vertical shift? A. f(x) + kB. kf(x)
C. f(x + k)
D. f(kx)

Answers

Given the function $f(x) = x^2$ and k = –3, consider all options:

A. $f(x)+k=x^2-3$ - this is translation down 3 units;

B. $kf(x)=-3x^2$ - this is reflection across the x-axis and stretch in the y-direction;

C. $f(x+k)=(x-3)^2$ - this is translation 3 units to the right;

D. $f(kx)=(-3x)^2$ - this is compression it in the x-direction.

The only possible option with vertical shift is option A.

when you are dealing with any function f(x)=x^w,

a vertical shift is:
f(x) = x^w+c (shift up)

therefore the answer is: A. f(x) + k

A boater travels 532 miles. Assuming the boat averages 6.3 miles per gallon, how many gallons of gasoline(to the nearest then of gallon) were used? plz show work

Answers

Answer:

84.4 gallons to the nearest tenth.

Step-by-step explanation:

Average usage = miles travelled / gallons used so:

6.3 = 532 / gallons used

Gallons used = 532 / 6.3

= 84.44.

Solve each equation for the indicated variable. u = -3a - 3 , for a

Answers

Answer:

$a = (u + 3)/(-3)$

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 3 to both sides of the equation:

u = -3a - 3

u (+3) = -3a - 3 (+3)

u + 3 = -3a

Next, divide -3 from both sides of the equation:

(u + 3)/-3 = (-3a)/-3

a = (u + 3)/-3

$a = (u + 3)/(-3)$ is your answer.

What Is the next number? 12 21 23 32 34 43

so, we add 11 to 12 and get 23, then we add 11 to 23 and get 34, now we have to add 11 to 34 and get 45, that is the next number:
12 21 23 32 34 43 45 54

The next number of the number series 12 21 23 32 34 43 would be; 54

We are given the series as;

12 21 23 32 34 43

First, we have to add 11 to 12

11 + 12 = 23,

then we add 11 to 23

11 + 23 = 34,

Now we have to add 11 to 34

11 + 34 =45,

This is the next number:

12 21 23 32 34 43 45 54
