Step-by-step explanation:
(f-g)(x) = f(x) - g(x)
the same applies to all other basic operations (like addition, multiplication, ...).
so,
(f-g)(x) = 4x² - 3 - (x + 1) = 4x² - 3 - x - 1 = 4x² - x - 4
Answer:
k = -7
Step-by-step explanation:
Find the difference of the y-values of both vertexes:
f(x): y = 1
g(x): y = -6
g(x) - f(x)
-6 - 1 = -7
