Answer:

Step-by-step explanation:

7√144 - 11√45 + 6√500

= 7(12) - 11√(9×5) + 6√(100×5)

= 84 - 11(3)√5 + 6(10)√5

= 84 - 33√5 + 60√5

Which statement best describes how to determine whether f(x) = x3 + 5x + 1 is an even function?
balandron [24]

<u>The right answer is:</u> Determine whether (-x)^3+5(-x)+1 is equivalent to x^3+5x+1


A function is said to be even if its graph is symmetric with respect to the y-axis. That is:

A \ function \ y=f(x) \ is \ \mathbf{even} \ if, \ for \ each \ x \ in \ the \ domain \ of \  f:\\ \\ f(-x)=f(x)


According to this definition, the statement that best describes if the function:

f(x)=x^3+5x+1

is even, is:


Determine whether (-x)^3+5(-x)+1 is equivalent to x^3+5x+1


By doing this, we have:

f(-x)=(-x)^3+5(-x)+1 \\ \\ \therefore \ f(-x)=-x^3-5x+1


As you can see:

f(x) \neq f(-x)


Conclusion:<em> </em><em>The function is not even.</em>
