Question

Can someone please help me! Fan and give medal

Answer 1

Part A: If it's linear, the terms are growing linearly (you can add the same number to each term to get the next term). If the terms are growing linearly (you can exponentiate to each term to get the next term), then it's exponential.
Part B: Basically f(n) = n + x (linear) or f(n) = n^y + z (exponential). (correct me if i'm wrong someone)
Part C: Using the equation, try to calculate the result by setting n to 20.
Hope that helps.

Answer 2

That helped me some, but I'm not entirely sure how to write functions or anything for this @rileywkong

Answer 3

Oh.

n is the starting point for all of the equations.
x, y, and z are different:
x and z are the numbers you add by to get the next term.
y is the power you raise by to get the next term (usually 2).
FYI: to write an equation you write f(x) = [your equation goes here].
