y=-6(x+7)^4 + 5

0=-6(x+7)^4 + 5

-5=6(x+7)^4

-5/6 =(x+7)^4

There are no x-intercepts??

**Reiny**, Friday, December 9, 2011 at 10:48amYou dropped the negative sign in front of the 6 in line 3 , so ....

-5 = -6(x+7)^4

(x+7)^4 = 5/6

x+7 = ± (5/6)^(1/4) , fourthroot of (5/6)

I get x = appr. ± .955
