Just replace 'x' in c(x) by d(x)
(cod) (x) = 4(x^2+5x) - 2 = 4x^2 +20x - 2
Thats it!

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
f(x) = x² + 9x - 6
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-x) = (-x)² + 9(-x) - 6
- [Order of Operations] Simplify: f(-x) = x² - 9x - 6
Answer:
1/60
Step-by-step explanation:
convert 2 hours into minutes = 120 minutes
simplify 20/120
1/60
The table on the left is <u>arithmetic</u>
This is because each term is increasing by the same amount (2) each time.
- 3+2 = 5
- 5+2 = 7
- 7+2 = 9
- 9+2 = 11
--------------------------------------------
The table on the right is <u>geometric</u>
Why? Because this time we are multiplying each term by the same value (2) to get the next term.
- 3*2 = 6
- 6*2 = 12
- 12*2 = 24
- 24*2 = 48
Both involve the number 2, but the first table uses addition while the second table uses multiplication.
The answer is 3.66 (it’s a positive number because the two negatives cancel each other out)
