The equation I chose is y=1/3(x^2)-14 with perpendicular equilateral triangles. The X-Intercepts are -6.48 and 6.48. The Y-intercept is -14. I'm aware that to solve for the area it's the integral from -6.48 to 6.48 of (sqrt(3)/4)(2x^2). I got the answer 306.964 and I'm pretty sure the answer is right. How would I enter that into google sheets?
