The graph of which function passes through (0,4) and has a minimum value at O fx) - sin(x) + 4
O f(x) - cos(x) + 3
O f(x) - -3 sin(x)
O fx) - 4 cos(x)

yes

step-by-step explanation:

yes

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.
