Functions graph a-c questions

Mathematics

o-na [289]2 years ago

a) The domain and range of the function are x ∈ (- ∞, 8) and y ∈ [- 3, + ∞).

b) The value of f(7) is equal to 2.

c) The values of x such that f(x) = 3 are x₁ = - 8, x₂ = - 1.6, x₃ = 3.

<h3>How to analyze a function based on a given graph</h3>

In this exercise we analyze and describe a series of features of a function, all derived from a given picture.

a) In the first part we must determine the domain and range of the function, the domain represents the set of values from the horizontal axis that belong that exist in the curve and the range is for the set of values from the vertical axis.

Then, the domain and range of the function are x ∈ (- ∞, 8) and y ∈ [- 3, + ∞).

b) The value of the function corresponds with the point of intersection between x = 7 and y = 2. Hence, the value of f(7) is equal to 2.

c) Now we must find the x-values such that f(x) = 3. After looking in the graph, we find three different solutions: x₁ = - 8, x₂ = - 1.6, x₃ = 3.

Find the distance between the points (0,-2) and (6,-6)
goldenfox [79]

Answer:

Formular:

length =  \sqrt{ {(x_{1} - x_{2} )}^{2}  +  {(y_{1} - y_{2} ) }^{2} }

x1 » 0

x2 » 6

y1 » -2

y2 » -6

l =  \sqrt{ {(0 - 6)}^{2}  +  {( - 2 - 6)}^{2} }  \\  \\ l =  \sqrt{ {( - 6)}^{2}  +  {( - 8)}^{2} }  \\  \\ l =  \sqrt{36 + 64}  \\  \\ l =  \sqrt{100}

for the √100 in surds:

l =  \sqrt{10 \times 10}  =  \sqrt{ {10}^{2} }  = ( {10}^{2} ) {}^{ \frac{1}{2} }  \\  \\ { \boxed{ \boxed{distance = 10 \:  \: units}}}

Identify the graph that represents the solution set to Inequality. Place the unused choices at the bottom.PLEASE HELP WITH THIS
kotykmax [81]

Answer:

Step-by-step explanation:

There are two ways to go about solving this problem, depending on your available time and fluency with the topic:

Solve it “properly”, by graphing the inequalities yourself, then comparing your graph to the available options.

Use the test-taking strategies of “ruling out answers that are clearly wrong”, followed by “use enough of what you know about the problem to select the correct answer.

Let’s walk through both, since you should be able to do both, as this problem looks very much like a practice problem for a standardized Algebra 1 test.

So! To graph a linear inequality, the steps include graphing the line, determining what type of line, and determining how it’s shaded, though the order of these steps is only important if you’re doing math in pen, which is a terrible idea.

The first inequality:
