Nora inherited a savings account that was started by her grandmother 25 years ago. This scenario is modeled by the function Alt) = 5000(1.013)+25, where Alt)
represents the value of the account, in dollars, years after the inheritance. Which
function below is equivalent to Aft)?
a) A(t) = 5000p(1.013)]3
b) A(t) = 5000[(1.013)' + (1.013)251
c) A(t) = (5000)*(1.013)25
-d) A(t) = 5000(1.013) (1.013)25

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.
