ORIGINAL PROBLEM- ( A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days:
f(n) = 8(1.05)n )

MY QUESTION-
what is the y intercept of the equation ( f(n) = 8(1.05)n )?

The y-intercept is 0 since it is the plant's initial height.

Actual the equation as written is misleading....

f(n) = 8(1.05)n    should be written as f(n) = 8(1.05)^n  I believe the n is an exponent

When n is zero the 1.05^0is equal to 1

thus f(n) = 8 times 1 equals 7
