F(x) = | 3x+1 | find the vertex of value function

PilotLPTM [1.2K]

Answer:

The vertex is the point $(-\frac{1}{3},0)$

Step-by-step explanation:

we know that

The general form of an absolute value equation is

$y=a\left|x-h\right|+k$

The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables h, and k, tell us how far the graph shifts horizontally and vertically

The vertex is the point (h,k)

we have

$f(x)=\left|3x+1\right|$

Rewrite the expression (3x+1)

$(3x+1)=\frac{3}{3} (3x+1)=3(x+\frac{1}{3})$

substitute

$f(x)=\left|3(x+\frac{1}{3})\right|$

$f(x)=3\left|(x+\frac{1}{3})\right|$

$a=3\\h=-\frac{1}{3}\\k=0$

therefore

The vertex is the point $(-\frac{1}{3},0)$

see the attached figure to better understand the problem

Consider the given rectangle with heightequals4timeswidth. Let x be the width of the rectangle. Write an expression for the per

Salsk061 [2.6K]

Answer:

<h3>The expression for the perimeter P is $P=\frac{784+h^2}{2h}$ feet.</h3><h3> Area=49=lx square feet ( here $x=\frac{h}{4}$ )</h3>

Step-by-step explanation:

Given that rectangle with height equals 4times width.

It can be written as

$h=4\times width$

Let x be the width of the given rectangle

Therefore $h=4\times x$

$h=4x$

$\frac{h}{4}=x$

Rewritting the above equation we get

$x=\frac{h}{4}$

<h3>To write an expression for the perimeter P of the given rectangle :</h3>

Also given that area of the rectangle is 49 square feet.

Area=49 square feet.

We know area of rectangle = lw square units.

<h3>Therefore area=49=lx square feet ( here area=49 and w= $x=\frac{h}{4}$ )</h3>

Rewritting we get

lx=49 square feet.

$l=\frac{49}{x}$

$=\frac{49}{\frac{h}{4}}$

$l=\frac{49\times 4}{h}$

<h3> $l=\frac{196}{h}$ feet</h3><h3>Perimeter P $=2(l+w)$ units </h3>

$P=2(\frac{196}{h}+\frac{h}{4})$

$P=\frac{2(196)}{h}+\frac{2(h)}{4}$

$=\frac{392}{h}+\frac{h}{2}$

$=\frac{392(2)+h^2}{2h}$

Use the method of disk or washer to set up, but do not evaluate, an integral for a volume of the solid obtained by rotating the

Sedbober [7]

Answer:

V = π /2 volume units

Step-by-step explanation:

Volume of y = √x bounded by y = x and y = 1

y = √x

limits of integration ( see Annex )

By simple inspection limits of integration are x = 0 to x = 1

or y = √x and y = x

solving these two equations

x = 0 y = 0 x = 1 y = ± 1

V = ∫ π*f(x)²*dx

V = π * ∫₀¹ x*dx = π * x²/2 |₀¹

V = π * (1/2) - 0

V = π /2 volume units
