The only equation that has 3 as the coefficient of x (a slope of 3) is ...
... d.) y = 3x+4
_____
Happily, it also goes through the given point.
... 5/2 = 3(-1/2) +4
... 5/2 = -3/2 + 8/2 . . . . true
F(x) = 2x² + x - 3
g(x) = x - 1
(f - g)(x) = (2x² + x - 3) - (x - 1)
(f - g)(x) = 2x² + (x - x) + (-3 + 1)
(f - g)(x) = 2x² - 2
The answer is D.
A --------¢ D
B --------¢ E
C --------¢ F
Just match like this buddy.
