Answer:
D
Step-by-step explanation:
-4 * -6 is -34
add 2 and you have -24
Answer:
Step-by-step explanation:
Please use " ^ " to denote exponentiation: f(x) = x^2 + 4x - 21.
This function has a graph which is a parabola that opens up.
Its vertex is found by completing the square:
x² + 4x + 4 - 4 - 21, or
(x + 2)² - 25
Comparing this to the standard equation
(x - h)² + k, we see that h = -2 and k = -25.
Thus, the vertex (and the minimum of this function) is (-2, -25).
Thus, the range is [-25, ∞ ). This being a polynomial function, it has no restrictions on the domain: the domain is (-∞, ∞ )
Step-by-step explanation:
Cone Volume = 1/3 ×( π r² h) h = 2 × diameter = 2 × 2 × r
Cone Volume = 1/3 ×( π r² h) h = 2 × diameter diameter = 2r
= 2 × (2 × r)
= 4r
Cone Volume = 1/3 ×( π r² 4r)
= (4 π r³ / 3)
Answer:
y = (x + 1.5)^2 + 1.75.
Step-by-step explanation:
y = x^2 + 3x - 4
Completing the square:-
y = (x + 1.5)^2 - (1.5)^2 - 4
y = (x + 1.5)^2 - 2.25 + 4
y = (x + 1.5)^2 + 1.75 (answer).
