The functions r and s are defined as follows. R(x)=x-1. And. S(x)=-x squared. Find the value of r(s(-2))
1 answer:
Answer:
-5
Step-by-step explanation:
"r(s(-2))" is a composition of functions. To evaluate this, we need to plug in "-2" into the function S(x) and then take that value and further plug it into R(x).
First, s(-2):
Now, we take the value (-4) and put it into R(x) to get our final answer:
Hence, r(s(-2)) = -5

Answer:
The required co-ordinate is (-2, -5).
Step-by-step explanation:
For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be: .
Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:
= (-2, -5)
The reflected point is (-2, -5).
Answer:
okay so you would make a line straight across the middle of the spherical shape. The line that goes all the way across is the diameter. If you were to cut that line in half that would be the radius.
Step-by-step explanation:
The first circle shown in the picture provided would be an example of diameter, and the second circle would be an example of the radius. You could just make up a value, for example say the diameter is 10, the radius would be 5.
