Answer:
The answer is (D) ⇒ 2x² - 2 ; domain: all real numbers
Step-by-step explanation:
∵ f(x) = 2x² + x - 3
∵ g(x) = x - 1
∴ (f - g)(x) = 2x² + x - 3 - (x - 1) = 2x² + x - 3 - x + 1
= 2x² - 2
∵ There is no value of x make the function undefined
∴ The domain is all real numbers
A Pascal triangle is the triangular way of expanding a binomial. So the best way in expanding that function is thru Binomial Theorem and the expanded for of it is 8x^3+48x^2+98x+64

Answer:
53.1°
Step-by-step explanation:
Let x represent the wangle of elevation from B to C
Reference angle = x
Opposite side to x = 16 - 4 = 12
Adjacent = 9
Apply trigonometric ratio to find x.
Thus:


(nearest tenth)
Angle of elevation from B to C = 53.1°
I believe it is C, as the graphs do look the same.
