Domain is the numbers you can use
range is the result of inputing the domain

an interesting fact is that the inverse of a function switches the domain and range

basically
the domain of f(x) becomes the range of f^-1(x)
the range of f(x) becomes the domain of f^-1(x)
so just find the domain and range of f(x)


f(x)=3x- \frac{1}{2}
there are no restrictions
all real numbers can be used
all real numbers can result


so the answer is domain and range for both is all real numbers

Solve for x.<br><br> 4(x−214)=−3.7<br><br> Enter your answer as a decimal in the box.<br><br> x =
andre [41]
X = 213.075
First you have to get rid of the 4 and since it’s multiplying you to the opposite and that’s dividing.
-3.7 divided by 4 = -0.925
X - 214 = -0. 925
Then you add 214 to -0.925 and get 213.075

I need help. What are the two numbers on the middle
Rina8888 [55]

Answer:

  Miles: 35; Gallons: 1

Step-by-step explanation:

The number of gallons can be any number of your choosing that is less than 12, which is the capacity of the tank. For the purpose here, 1 is a convenient number. To find the corresponding number of miles (m), you need to solve the proportion ...

  420/12 = m/1

  35 = m

  (miles, gallons) = (35, 1) . . . a suitable choice for the table values

__

<em>Additional comment</em>

If your sense of symmetry is offended by choosing 1 for Gallons, you can choose 10, a number halfway between 12 and 8. In that case, your proportion is ...

  420/12 = m/10   ⇒   m = 350

Then, your entry would be ...

 (miles, gallons) = (350, 10)

The graph of f(x) = x2 is translated to form g(x) = (x – 2)2 – 3. Which graph represents g(x)?
cupoosta [38]

Answer:

See attached picture

Step-by-step explanation:

When functions are transformed there are a few simple rules:

• Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).

• Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).

• Multiplying the function by a number less than 1 compresses it towards the x-axis.

• Multiplying the function by a number greater than 1 stretches it away from the x-axis.

The equation for g has been subtracted inside the parenthesis by 2 which will shift the graph 2 units to the right.

The equation for g has also been subtracted outside the parenthesis by 3 which will shift the  graph 3 units down.

The graph is shown in black while f(x) is show in purple in the attached picture.
