The first one is the second one is All real numbers Step- by-step explanation:
1. Anything raised to the " zeroth" power is always 1
2. Because 7 is being raised to the zeroth power, the number inside the parentheses becomes 1. Now x can equal anything, 1 times itself will always equal 1, no matter how many times you multiply them.

Answer:
B
Step-by-step explanation:
Given
x² - 12x + 35
Consider the factors of the constant term ( + 35) which sum to give the coefficient of the x- term
The factors are - 5 and - 7, since
- 5 × - 7 = + 35 and - 5 + - 7 = - 12, hence
x² - 12x + 35 = (x - 5)(x - 7) → B
F'(x)= 4 (2x+3)^3 times 2 = 8 (2x+3)^3 .
