Answer:
The number 30 is composite
Step-by-step explanation:
It is a composite because multiple numbers can go into 30 like 6 and 5 or 3 and 10. A prime number is like 3 because only 3 and 1 can go into it. 2 and 5 and 7 is also a prime number.
For discontinuity of the function:
x² - 7 x - 8 ≠ 0
x² - 8 x + x - 8 = 0
x ( x - 8 ) + ( x - 8 ) ≠ 0
( x - 8 ) ( x + 1 ) ≠ 0
The points of discontinuity are: x = - 1 and x = 8.
As for the Domain of the function:
x ∈ ( - ∞, - 1 ) ∪ ( - 1 , 8 ) ∪ ( 8, +∞ ).
X^2 2x + 1 = (x + 1)^2
x is replaced by x + 1
the translation is 1 unit to the left
