the root for which the graph of cross the x-axis i.e. value of y or f(x) = 0 is
.
<u>Step-by-step explanation:</u>
We have , f(x) = (x + 4) 6(x + 7)5 i.e.. We need to find root for which the graph of
cross the x-axis i.e. value of y or f(x) = 0. Let's solve this:
⇒
⇒
⇒
Which means either or ,
. That means the root for which the graph of
cross the x-axis i.e. value of y or f(x) = 0 is
or
. ∴ From given options , the root for which the graph of
cross the x-axis i.e. value of y or f(x) = 0 is
.
