The graph f(x)=x^1/3 is symmetric about the y-axis . True or false justify your answer
vlabodo [156]

Answer:

False

Step-by-step explanation:

Upon graphing the function with any given graphing calculator, the function does not have symmetry across the y axis, as the graph is going below the x axis on one side of the y axis, and above the x axis on the other side of the y axis.

What are the two solutions of 2x2 = –x2 – 5x – 1?
77julia77 [94]

Answer:

The answer is

<h3>x =  \frac{ - 5 +  \sqrt{13} }{6}  \:  \:  \:  \: or \:  \:  \: x  =  \frac{ - 5 -  \sqrt{13} }{6}</h3>

Step-by-step explanation:

2x² = - x² - 5x - 1

<u>Rearrange the terms and simplify</u>

That's

2x² + x² + 5x + 1 = 0

3x² + 5x + 1 = 0

Using the quadratic formula solve the equation

That's

<h3>x =  \frac{ - b\pm \sqrt{ {b}^{2}  - 4ac} }{2a}</h3>

From the question

a = 3 , b = 5 , c = 1

So we have

<h3>x =  \frac{ - 5\pm \sqrt{ {5}^{2} - 4(3)(1) }}{2(3)}  \\  =  \frac{ - 5\pm \sqrt{25 - 12} }{6}  \\   = \frac{  - 5\pm \sqrt{13} }{6}</h3>

We have the final answer as

<h3>x =  \frac{ - 5 +  \sqrt{13} }{6}  \:  \:  \:  \: or \:  \:  \: x  =  \frac{ - 5 -  \sqrt{13} }{6}</h3>

Hope this helps you
