Describe the continuity of the graphed function

marusya05 [52]

we know that

Any function f(x) is continuous at x=a only if

$\lim_{x \to a-} f(x) = \lim_{x \to a+} f(x)=f(a)$

We can see that this curve is smooth everywhere except at x=3

so, we will check continuity at x=3

Left limit is:

$\lim_{x \to 3-} f(x) = -\infty$

Right limit is:

$\lim_{x \to 3+} f(x) = +\infty$

Functional value:

$f(3)= DNE$

we can see that left limit is not equal to right limit

so, limit does not not exist

so, this function is discontinuous at x=3

Since, limit does not exist

so, there will be non-removal discontinuity at x=3

so, option-C........Answer

Math question please show work due today last day to submit Assignments or I fail please help

Answer:

$\$128.43$

Step-by-step explanation:

Since the cost for border paper is given in terms of feet and the dimensions of the gym are given in meters, we want to convert them to the same unit. Let's choose to convert feet to meters since that would be only one conversion:

$15\:\mathrm{ft}=4.572\:\mathrm{m}$

Therefore, the cost of border paper is $6.99 pet 15 feet or $6.99 pet 4.572 meters.

Since the gym is rectangular, the gym's perimeter is equal to:

$p=15+27+15+27,\\p=2(15)+2(27)=84\:\mathrm{m}$

Therefore, the cost of the total border paper for the gym is equal to:

$\text{cost}=\frac{84}{4.572}\cdot 6.99\approx \boxed{\$128.43}$

Identify the domain of the function shown in the graph.

ivanzaharov [21]

For this case, we find the equation of the line, for this we look for points where the line passes:

$(x1, y1) = (- 2,0)\\(x2, y2) = (- 10, -4)$

We found the slope:

$m = \frac {y2-y1} {x2-x1} = \frac {-4-0} {- 10 - (- 2)} = \frac {-4} {- 10 + 2} = \frac {- 4} {- 8} = \frac {1} {2}$

Thus, the equation of the line is:

$y = \frac {1} {2} x + b$

We substitute a point to find "b":

$0 = \frac {1} {2} (- 2) + b\\0 = -1 + b\\b = 1$

Finally:

$y = \frac {1} {2} x + 1$

Now, the domain is given by all the values for which the function is defined.

It is observed that "x" can take any value, that is, it is defined for all real numbers.

A student says the first step of the proof is "Reflect △ABC in AB←→ to create △ABC′." Which of the following statements logicall

ollegr [7]

Reflecting the triangle ABC implies that the new position would be a mirror of the previous position

The statement that logically comes next is (c) Translate triangle ABC, so that point A maps to point W

<h3>How to determine the next step</h3>

After reflecting the triangle ABC, the next step is to map point A to point W on the coordinate plane.

This is done by translating the triangle ABC i.e. by shifting or moving the triangle ABC so that points A and W would be on the same point

Hence, the statement that logically comes next is (c)
