Question

How do you solve this?

Answer 1

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!

Answer 2

Answer:

f(- 10) = 74

Step-by-step explanation:

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

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