Find the standard matrix representation for the following linear transformation. l : r2 → r2 is the linear transformation that rotates each x ∈ r2 by 60º in the counterclockwise direction and then reflects about the line x2 = x1 .

answer:

c. the third graph

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

i believe that the slope of the line is -5
