Question

Evaluate the given equation for the indicated function values. pls help

Answer 1

The answer in each numeral is:

1. f(4) = 28
2. f(10) = -19
3. f(-5) = -33
4. f(9) = -9

Explanation:

To obtain the result in each case, you must replace the variable (n) by the value that appears in the second case, I'll explain it with the first exercise:

• 1. f(n) = 5n + 8
• f(4) = ?

As you can see, in the second doesn't appear f(n), but f(4), that means you must replace the "n" in the equation by 4, if we do this, we obtain:

• 1. f(4) = 5*(4) + 8
• f(4) = 20 + 8
• f(4) = 28

The first answer is 28, now we'll continue with the next exercises:

• 2. f(n) = -2n + 1
• f(10) = -2*(10) + 1
• f(10) = -20 + 1
• f(10) = -19

• 3. f(n) = 6n - 3
• f(-5) = 6*(-5) - 3
• f(-5) = -30 - 3
• f(-5) = -33

• 4. f(n) = -n
• f(9) = -9

In this form, you can prove the answers are: 28, -19, -33, and -9 respectively.
