Given f(x) = the quantity of x minus 7, divided by 3, solve for f−1(4).

Solution:

f(x)=

Or , y =

→ 3 y = x-7

→ x = 3 y +7-----(1)

Now replace x by y in equation 1 ,to get the inverse of f(x)

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
