Question

How do you solve this?

Answer 1

f(- 10) = 74

Explanation:

To find f(- 10) , substitute n = - 10 into f(n) , that is

f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74

Answer 2

Hello there!

We are given a function below:

`\displaystyle \large{f(n) = - 7n + 4}`

To find f(-10), substitute n = -10.

`\displaystyle \large{f( - 10) = - 7( - 10) + 4}`

Evaluate the f(-10)

`\displaystyle \large{f( - 10) = 70 + 4}`

Recall

• Negative × Negative = Positive

Therefore,

`\displaystyle \large{f( - 10) = 74}`

f(-10) = 74

Let me know if you have any questions!
