I am assuming you meant to write f(x) = 3^x -2
f(3) = 3^3 - 2 <=>
f(3) = 27 - 2 <=>
f(3) = 25
Answer:
Part A) The slope is 
Part B) The equation of the line is 
Step-by-step explanation:
Part A) What is the slope of the graph?
we know that
The formula to calculate the slope between two points is equal to

Looking at the graph it takes any two points
(-2,0) and (0,-1)
substitute the values in the formula



Part B) Write an equation for the line
we know that
The equation of the line in slope intercept form is

where
m is the slope
b is the y-coordinate of the y-intercept
we have

----> the y-intercept is the point (0,-1)
substitute

Step-by-step explanation:
Answer: 6+ 2y
Step-by-step explanation:
The tree starts off at 6 feet so that doesn't change but it grows constantly 2 feet per year so add 2y to 6 and plug in the number of years for y.
X - $0.25(8) =$28
x - $2.00 = $28
x -2 +2 = $28+2
x = $30
You would have started out with $30
