At which root does the graph of f(x) = (x+4)6(x + 7)5 cross the x axis?
Licemer1 [7]

Answer:

x = -7

Step-by-step explanation:

Our function is f(x) =(x+4)^6(x+7)^5. Notice that our possible roots are when x + 4 = 0 and when x + 7 = 0. So, our roots are -4 and -7.

However, the power above x + 4 is even, meaning the graph will simply <em>touch</em> the x-axis at x = -4, but not pass through. The power above x + 7, though, is odd, which means the graph will <em>cross</em> the x-axis.

Thus, the answer is x = -7.
