Recall that for all t,
cos²(t) + sin²(t) = 1
Now,
x = 5 cos(t) - 7 ⇒ (x + 7)/5 = cos(t)
y = 5 sin(t) + 9 ⇒ (y - 9)/5 = sin(t)
so that substituting into the identity above, we get
((x + 7)/5)² + ((y - 9)/5)² = 1
which we can rewrite as
(x + 7)²/25 + (y - 9)²/25 = 1
(x + 7)² + (y - 9)² = 25
and this is the equation of a circle centered at (-7, 9) with radius 5.

Answer:
The range of function for domain {-2,3,8} is {11,1,-9}
Step-by-step explanation:
Given function is:

We have to find the range for given values.
To find the range, we will put the domain values one by one in the function to find the range.
So,
Putting x=-2, 3, 8

The range of function for domain {-2,3,8} is {11,1,-9}
