please show on graph (with x and y coordinates) state where the function x^4-36x^2 is non-negative, increasing, concave up

babunello [35]

Answer:

$y'' =12x^2 -72=0$

And solving we got:

$x=\pm \sqrt{\frac{72}{12}} =\pm \sqrt{6}$

We can find the sings of the second derivate on the following intervals:

$(-\infty$ Concave up

$x=-\sqrt{6}, y =-180$ inflection point

$(-\sqrt{6}$ Concave down

$x=\sqrt{6}, y=-180$ inflection point

$(\sqrt{6}$ Concave up

Step-by-step explanation:

For this case we have the following function:

$y= x^4 -36x^2$

We can find the first derivate and we got:

$y' = 4x^3 -72x$

In order to find the concavity we can find the second derivate and we got:

$y'' = 12x^2 -72$

We can set up this derivate equal to 0 and we got:

$y'' =12x^2 -72=0$

And solving we got:

$x=\pm \sqrt{\frac{72}{12}} =\pm \sqrt{6}$

We can find the sings of the second derivate on the following intervals:

$(-\infty$ Concave up

$x=-\sqrt{6}, y =-180$ inflection point

$(-\sqrt{6}$ Concave down

$x=\sqrt{6}, y=-180$ inflection point

$(\sqrt{6}$ Concave up

Can you help me on 2,3and 4

Ludmilka [50]

1.n represents the number of tickets she bought.

2.27.75n represents the total cost of n tickets

3.Without the handling fee Olga paid 138.75

4.To get 27.75n by itself on one side of the equation you can move 5.5 from the left to right of the equation

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

n is the total number of tickets Olga bought.

27.75n represents the total cost of n tickets.It is given in the question that one ticket costs $27.75 and thus n number of tickets will cost $27.75 n.

The handling fee is 5.5

27.75n+5.5=144.25

27.75n=144.25-5.5=138.75

without the handling fee Olga will pay $138.75
