Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Remember that the radicand must be greater than or equal to zero
so

solve for x
subtract 2 both sides

The domain is the interval [-2,∞)
All real number greater than or equal to -2
For x=-2

so
The range is the interval [0,∞)
All real number greater than or equal to 0
Find the y-intercept
Remember that the y-intercept is the value of y when the value of x is equal to zero
For x=0



The y-intercept is the point (0,4.243)
therefore
The graph in the attached figure
Variables next to each other can be regarded as being multiplied by each other, so another way to rewrite this could be A * A * A * A * B * B. From there, you can reach
Answer:
Below in bold
Step-by-step explanation:
∫ dx / (x^2√(9-x^2))
Substitute x = 3sinu and dx = 3cosu du
then the √(9-x^2) = √( 9 - 9sin^2u) = 3 cos u and u = arcsin(x/3)
= 3 ∫(csc^2 u du )/ 27
= 1/9 ∫(csc^2 u du
= -1/9 cot u
= -√9-x^2) / 9x.
