Question

F{x) = a (x − a}² + 1]

In the function f defined above, a > 1. Which of the
following best represents the graph of f in the
xy-plane?

Answer 1

Explanation:

1 f(x) = ax (x − a)² + 1

Take the derivative

f'(x) = d/dx ( a x( x -a) ²+1

Use differentiation rules

f' x = ax2 x-a +0

Simplify

= f'(x)=2ax-2a²
