What is the translation of t< 5,-1>

T<x, y>

x - translation (x > 0 - x units right; x < 0 - x units left)

y - translation (y > 0 - y units up; y < 0 - y units down)

T<5, -1>

5 units right and 1 unit down

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
