Question

At which root does the graph of f(x)=(x+4)^6(x+7)^5 cross the x axis​

Answer 1

Answer would be A: -7

Answer 2

-7.

Explanation:

At the point -4 the graph just touches the x axis ( as its an even power) but at x = -7 it crosses the x axis ( because of the odd power 5).

The graph rises from the left and pass through the x axis at (-7,0).
