-1 undefined since we cannot take the sqrt of a negative number
0 0
1 -1
4 -2
Step-by-step explanation:
f(x) = sqrt(x)
A reflection over the x axis is-f(x)
g(x) = -sqrt(x)
x -sqrt(x)
-1 undefined since we cannot take the sqrt of a negative number
0 0
1 -1
4 -2
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:
