Hello there!
We are given a function below:
[tex] \displaystyle \large{f(n) = - 7n + 4}[/tex]
To find f(-10), substitute n = -10.
[tex] \displaystyle \large{f( - 10) = - 7( - 10) + 4}[/tex]
Evaluate the f(-10)
[tex] \displaystyle \large{f( - 10) = 70 + 4}[/tex]
Recall
- Negative × Negative = Positive
Therefore,
[tex] \displaystyle \large{f( - 10) = 74}[/tex]
f(-10) = 74
Let me know if you have any questions!
