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
