Choose the graphic representation of the quadratic function f(x) = x2 – 8x + 24.

larisa86 [58]

Refer the attached figure for the graphic representation of the given quadratic equation.

<u>Step-by-step explanation:</u>

Given expression:

$f(x)=x^{2}-8 x+24$

To find:

The graphic representation of the given quadratic function

For solution, plot the graph to the given quadratic equation.

The standard form of the equation is

$y=a x^{2}+b x+c$

When comparing with given quadratic equation,

a = 1, b = - 8, c = 24

Axis of symmetry is $x=\frac{-b}{2 a}$

By applying the values, the axis of symmetry of given equation is

$x=\frac{-(-8)}{2(1)}=4$

The vertex form of quadratic equation is $f(x)=a(x-h)^{2}+k$

Where, (h,k) are the vertex.

Convert the quadratic equation into vertex form.

By completing the square,

$f(x)=x^{2}-8 x+24$

$f(x)=\left(x^{2}-2(4) x+4^{2}\right)-4^{2}+24$

$f(x)=(x-4)^{2}+8$

On comparison,

(h , k) = (4 , 8)

Now, plot the equation with vertex (4,8) [refer attached figure].

33762 to the nearest thousand?

Reil [10]

Answer:

34,000

179,400

39,900

Step-by-step explanation:

In the number 33,762, the 3 is in the thousands place, so we look to the number behind it. If it is less than 5, we round down, and if it is more than 5 we round up.

Since 7 is more than 5, we round up, so our rounded number would be

34,000

Let’s use this logic for the rest of these numbers

179,406

4 is in the hundreds

Previous number in 0 which is less than 5, so it rounds down

179,400

39,994

9 is in the tens place

Previous number is 4 which is less than 5, so it rounds down

39,990
