The given numbers ordered from least to greatest is:

{√7 , 2.8..., π, √17, 4.6}

<h3>How to order the numbers from least to greatest?</h3>

First, we need to write all the given numbers in decimal form so we can accurately compare them.

The numbers are:

{4.6, √7, π, 2.8..., √17}

Rewriting all of these in decimal form:

√7 = 2.64

π = 3.14159265....

√17 = 4.12

Then the numbers are:

{4.6, 2.64, 3.14159265...., 2.8..., 4.12}

Now is easier to order these numbers, ordering them from least to greatest we will get:

{2.64, 2.8..., 3.14159265...., 4.12, 4.6}

Now, using the original notation we get:

{√7 , 2.8..., π, √17, 4.6}

What is the equation of the axis of symmetry do the quadratic function f(x) = -(x+4) (x-1)

miv72 [106K]

9514 1404 393

Answer:

x = -3/2

Step-by-step explanation:

The zeros of the function are the values of x that make the factors zero:

x = -4, x = 1

The axis of symmetry is the vertical line halfway between these zeros.

x = (-4 +1)/2 = -3/2

The equation of the axis of symmetry is x = -3/2.
