The function y=x^4+3x^2-5 is symmetrical across some axis. Determine, algebraically, the axis of symmetry. Create a table of values and use the function's symmetry to create a graph of the function. Show all work. My classes are online and come directly from a text book. The pages that have been shared with me about symmetry don't actually show anything about finding the axis of symmetry (at least not in this wording) and I am completely confused. Help?

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.

step-by-step explanation:

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
