What is the domain for the piece of the function represented by f(x) = x + 1? x < –1 –1 ≤ x ≤ 1 1 ≤ x < 2 x > 1
lapo4ka [179]

<em>Note: As you missed to mention the graph for f(x) = x + 1 from where we had to check which option defines the accurate graph. But, after a little research, I was able to get the graph of this question, and hence attaching the graph. So, I am answering based on that graph which, anyways, would clear your concept about determining the domain of the function that shows in a graph. </em>

Answer:

x > 1 is the domain of the f(x) = x + 1.

Step-by-step explanation:

A domain is the set of all x values that a function passes through. It means a domain is set of all input values where the function is defined, meaning whatever you input the x value, for every x-value there is only one y-value that corresponds to it.

So, now lets talk about the given function f(x) = x + 1 and its graph as shown in attached figure. Carefully observe the top right part of the graph of f(x) = x + 1. It is validating the condition of x > 1.

For example,

Just input some x values, greater than 1 i.e. x > 1, in f(x) = x + 1 to determine the output values.

For example, for x > 1

  • For x = 2, f(x) = 3. So, the graph must pass through of P(2, 3)
  • For x = 3, f(x) = 4. So, the graph must pass through of P(3, 4)
  • For x = 4, f(x) = 5. So, the graph must pass through of P(4, 5)

and so on.

So, the top right part of the graph of f(x) = x + 1 is validating the condition of x > 1 as it is passing through P(2, 3), P(3, 4) and P(4, 5) etc. and so on.

So, x > 1 is the domain of the f(x) = x + 1.

If 1 yard = 3 feet and 1 mile = 5,280 feet, how many yards are there in 2 miles? 2,640 yards 3,520 yards 10,560 yards 31,680 yar
fiasKO [112]

To solve this, you first have to find the number of yards in one mile.

If three feet = 1 yard, and 5280 ft = 1 mile, all you have to do to find the number of yards in a mile is divide 5280 feet by 3 feet.

You end up with 1760 yards in 1 mile.

To find the number of yards in 2 miles, all you would have to do is multiply 1760 by 2

<h3>1760 x 2 = <u>3520 yards</u></h3>

Write an equation for the number of points, y Enrique scores on the test when he answers x questions correctly.
kramer
<span><u><em>Answer:</em></u>
1. 3x = y
2. 7x= y.
<span>
<u><em>Explanation:</em></u>
If x is the amount of points each question that is answered correctly received then the coefficient that x is multiplied by will be the amount for each test.

For the first equation we have 3 as the amount answered correctly time x the points each one is worth = total points y.

For the second equation we have 7 as the amount answered correctly time x the points each one is worth = total points y .

#7:

It means to solve for y.


#8:

We can write:

l = w + 2

Because it says the length is 2 more than the width.
