Connecting exponential graphs with contexts
Problem
A sample of bacteria was placed in a petri dish. The number of bacteria changes exponentially over time.
The graph describes the number of bacteria over time (in hours).
An increasing exponential function passes through the point (0, 50) and the point (1, 60).
An increasing exponential function passes through the point (0, 50) and the point (1, 60).
What was the sample's initial size?
bacteria

i dony know

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.
