The average annual salary for a teacher nationally is $58,353. This is projected to increase 2% per year for the next 4 years. What will your projected annual salary be in four years?

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

where

y is the average annual salary

x is the number of years

r is the rate of change

a is the initial value

In this problem we have

substitute

For x=4 years

2

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.
