Is the function f(x) x³-11x odd even or neither

Mathematics

Paul [167]3 years ago

Answer:

Step-by-step explanation:

A function is odd if f(-x) = -f(x)

A function is even if f(-x) = f(x)

And neither if neither are true.

In this case if we plugged in a negative x here

f(-x) = (-x)^3 - 11(-x)

f(-x) = -x^3 + 11

Therefore, this function is odd because if we pulled out a negative one again we would get back the original function. Or in other words f(-x) = -f(x) for f(x) = x^3 - 11x

Identify all of the real fifth roots of 1024.

V125BC [204]

Answer:

Real fifth root of 1024 is 4.

Step-by-step explanation:

We have to find the value of real fifth root of 1024.

For this let fifth root of 1024 = x

Therefore $x^{5} = 1024 = 4^{5}$

Or $x^{5}=4^{5}$

Therefore x = 4

X= 4 is the right answer.

Which expression is the correct translation of the following word phrase?

Llana [10]

Hey, there!

The parentheses would make it multiplication
The word sum means add
A number was unknown, so we will label it as "x"

So, let's see what we're working with here!

If you chose "Option A" the question would be "five multiplied by a number and the sum of 3" (that doesn't give you the right answer"
For B. same thing with option A
For "Option C" its not asking you "a number with sum of three times five"

So, this leaves "Option D." as your answer because 3 is getting multiplied by the sum of some number and five

Good luck on your assignment and enjoy your day!

On the set of axes below, draw the graph of y=x^2-4x-1

never [62]

9514 1404 393

Answer:

axis of symmetry: x = 2

see below for a graph

Step-by-step explanation:

You can complete the square to put the equation in vertex form.

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

y = (x -2)^2 -5 . . . . . . vertex is (2, -5)

The equation of the axis of symmetry is the equation of the vertical line through the vertex:

x = 2 . . . . . axis of symmetry

Points on the graph are easily found by using integer values on either side of x=2. Points on one side of the axis of symmetry are mirrored on the other side of it.
