Solution:
Here we are given with a graph.
we have been asked to find the value of x for which
As we know that , to find the value of x for the given value of f(x), we need to look onto the vertical axis, and mark a dot on the given value now draw a line perpendicular to vertical axis so that it cut the given straight line, and where they intersect draw another line perpendicular to the horizontal axis and you will get the value where it crosses the horizontal axis.
Hence we get x=5, then f(x)=7.
