For what values of x is the graph of y equals negative 3 divided by the quantity 4 plus x concave downward?
Elena-2011 [213]

We are given our function as

y=\frac{-3}{x+4}

For finding concavity , firstly we will find second derivative

y'=\frac{d}{dx}\left(\frac{-3}{x+4}\right)

=-3\frac{d}{dx}\left(\frac{1}{x+4}\right)

=-3\left(-\frac{1}{\left(x+4\right)^2}\right)\cdot \:1

y'=\frac{3}{\left(x+4\right)^2}

now, we can find derivative again

y''=\frac{d}{dx}\left(\frac{3}{\left(x+4\right)^2}\right)

=3\frac{d}{dx}\left(\left(x+4\right)^{-2}\right)

y''=3\left(-\frac{2}{\left(x+4\right)^3}\right)\cdot \:1

y''=-\frac{6}{\left(x+4\right)^3}

now, we can know second derivative is undefined when denominator =0

so, we set denominator =0

and then we can solve for x

x+4=0

x=-4

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:

(-4,\infty)
