Answer:
(- 1, 2)
Step-by-step explanation:
Given a quadratic in standard form y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
f(x) = x² + 2x + 3 ← is in standard form
with a = 1 and b = 2, hence
= -
= - 1
Substitute x = - 1 into f(x) for corresponding value of y
f(- 1) = (- 1)² + 2(- 1) + 3 = 1 - 2 + 3 = 2
vertex = (- 1, 2 )
Cube root of 1728 is 12 and on multiplying it by cube root of 14903 we get 295.306.
<u>Solution: </u>
Need to calculate and then multiply the result by
Let us first evaluate
As need to multiply 12 by
On solving , we get
Hence cube root of 1728 is 12 and on multiplying it by cube root of 14903 we get 295.306.
