3x²-4x+7 how do I find the domain?

1 answer:

8 0

The domain of this equation is the lowest x value to the highest x value. For example: lowest is -4 and highest is 3. You would write it as [-4,3]

For this equation, the domain is (-infinity,infinity) because there is no lowest or highest x value.

It's a linear function with y-intercept = 12.

The slope-intercept form:

$f(x)=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

Let's read the coordinates of two points on the graph:

(2, 15) and (4, 18)

Substitute to the formula of a slope:

$m=\dfrac{18-15}{4-2}=\dfrac{3}{2}=1.5$

We have the equation of a line:

$\boxed{f(x)=1.5x+12}$

We need calculate the value of function for x = 1 and x = 20.

Substitute:

$f(1)=1.5(1)+12=13.5$

$f(20)=1.5(20)+12=30+12=42$

$12 is the "Fixed Fee", therefore the discounted entrance fee to the art museum is

$\$13.50-\$12.00=\$1.50$

The total cost is $42.00 after 20 visits.

BRAINLIEST!!!!<br><br><br> Identify the equation of the translated graph in general form

RUDIKE [14]

Answer:

Hyperbola:

$x^2-y^2-8x+6y-1=0$

Step-by-step explanation:

the given hyperbola has equation:

$x^2-y^2=8$

This is an equation of a hyperbola centered at the origin.

This hyperbola is translated so its center is now at T(4,3)

$(x-4)^2-(y-3)^2=8$

We expand to get:

$x^2-8x+16-(y^2-6y+9)=8$

$x^2-8x+16-y^2+6y-9=8$

$x^2-8x-y^2+6y+7=8$

$x^2-8x-y^2+6y+7-8=0$

$x^2-y^2-8x+6y-1=0$

Please help me out with this

Ivanshal [37]

Answer:

374.1

Step-by-step explanation:

Area of Hexagon = $\frac{3\sqrt{3} }{2} * a^{2}$

The ' a ' is the side length.

So now we just plug in the values

$\frac{3\sqrt{3} }{2} *12^{2}$ = 374.12
