Good evening.
We want:
The function is <em>not continuous</em> in 3, and f(3) = 7, but, as we approach to 3 from right, we are always in
f(x) = 3.
We can approach to indefinitely close to x = 3 from right, and the function will be always in 3. Therefore, we conclude that:
The answer is <span>b.12

According to the Pythagorean theorem the square of the hypotenuse (c) is the sum of the squares of the legs (a and b):
c² = a² + b²
We have:
a = 3x
b = 15
c = 3x + 3
Now, let's replace these parameters:
c² = a² + b²
(3x + 3)² = (3x)² + 15²
(3x)² + 2 * 3x * 3 + 3² = 9x² + 225
9x² + 18x + 9 = 9x² + 225
Rearrange:
9x² - 9x² + 18x = 225 - 9
18x = 216
x = 216 / 18 = 12
