<h3>Number 1</h3>
First of all, we need to multiple the separated function.

So the right answer is <u>A</u>
━━━━━━━━━━━━━━━━━
<h3>Number 2</h3>
the graph has four zeros at :
After that we make them equal with 0, here is the thing:
x = -a is equal with x + a = 0
So we can conclude that :
- -4 → x + 4 = 0
- -2/3 → 3x + 2 = 0
- 0 → x = 0
- 9 → x - 9 = 0
Then we substitute them to a function :
x(x + 4)(3x + 2)(x - 9) = 0
3x⁴ - 13x³ - 118x² - 72x = 0
Then we looking on the option which one is equal with the answer above.
The right answer is <u>B</u>

Hope It Helps!
So the closest integer above the square root of 3 is 2, and the closest integer below the square root of 89 is 9. (square root of 4 and 81, respectively.)
So we just want to add together all numbers between (including) 2 and 9.
So,
2 + 3 + 4 + 5 + 6 + 7 + 8 + 9
Or,
11 * 4
