Answer:

A) 48

B) -30

Step-by-step explanation:

Hello!

Part A

To compute f(-1) and f(5), we simply replace x with -1 and -5.

Calculate

  • [tex]f(-1) + f(5)[/tex]
  • [tex]((-1)^2 - 1 + 9)+ (5^2 +5 + 9)[/tex]
  • [tex](9)+(39)[/tex]
  • [tex]48[/tex]

The answer to A is 48

Part B

We have the values for f(-1) and f(5), so we just switch the operation

  • [tex](9) - (39)[/tex]
  • [tex]-30[/tex]

The answer to B is -30
