Which number has a 9 that is 1/10 the value of the 9 in 296?

1 answer:

5 0

Can i have the answers?
It would be something like this

129 the nine would be in one spot to the right of the other nine since it is 1/10 and any fraction number means moving the digit right and a whole number would mean moving to the left pls give brainliest

Answer:

$y=4x^2-8x-4$

Step-by-step explanation:

<u>Quadratic Function</u>

The quadratic function can be expressed in the following form:

$y=a(x-x_1)(x-x_2)$

Where a is a real number different from 0, and x1, x2 are the roots or zeroes of the function.

From the conditions stated in the problem, we know

x_1=1+\sqrt{2}, \ x_1=1-\sqrt{2}

Substitute in the general formula above:

$y=a[x-(1+\sqrt{2})][x-(1-\sqrt{2})]$

Operate the indicated product

$y=a(x^2-2x-1)$

To find the value of a, we use the y-intercept which is the value of y when x=0, thus

$y=a(0^2-2(0)-1)=-4$

It follows that

$a=4$

Thus, the required quadratic function is

$y=4(x^2-2x-1)$

Or, equivalently

$\boxed{y=4x^2-8x-4}$

Write the inverse of f(x)=x2+4

Over [174]

F(x) = x² + 4
y = x² + 4

First, I reverse the equation to be
x² + 4 = y

Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)

Last, change into invers function
f⁻¹(x) = √(x - 4)
