We are given our function as
For finding concavity , firstly we will find second derivative
now, we can find derivative again
now, we can know second derivative is undefined when denominator =0
so, we set denominator =0
and then we can solve for x
now, we can draw a number line and locate x=-4
and then we can find sign of second derivative on each intervals
so,
Concave downward interval:
Y+7= -(2/3)x+6)
First distribute the -1.
y+7= -(2/3)x-6
Then subtract 7 from both sides to isolate y.
y= -(2/3)x-13
Final answer: f(x)= -(2/3)x-13
