Question

Does anyone know what it means when there's an 'n' outside of the parentheses? I'd really appreciate the help.​

Answer 1

• f(3) = -8
• f(0) = 1

Given :

• 
  `f(n) = ( - 2) {}^(n)`

To find :

• 
  `f(3)`
• 
  `f(0)`

Solution :

In the given function, n is the indices of the base (-2).

Plugging in the value of n as 3,

• 
  `f(3) = ( - 2) {}^(3)`
• 
  `f(3) = - 2 * - 2 * - 2`
• 
  `f(3) = - 8`

Thus, f(3) = -8.

Plugging in the value of n as 0,

• 
  `f(0) = ( - 2) {}^(0)`
• 
  `f(0) = 1`

Thus, f(0) = 1.
