A net<span> is the shape that is formed by unfolding a three-dimensional </span>figure<span>. In other words, a </span>net<span> is composed of all of the faces of the </span>figure<span>. Notice that the </span>net<span> shown here is composed of 4 triangles and 1 rectangle, or 4 triangular faces and one rectangular base</span>
Finding the axis of symmetry.
1) Identify a, b, and c in the equation
f(x) = 4x² - 1 ⇒ a = 4 ; b = 0 ; c = -1
g(x) = x² - 8x + 5 ⇒ a = 1 ; b = -8 ; c = 5
h(x) = -3x² - 12x + 1 ⇒ a = -3 ; b = -12 ; c = 1
2) Formula of the axis of symmetry
x = -b/2a
f(x) ⇒ x = -0/2(4) = 0
g(x) ⇒ x = -(-8)/2(1) = 8/2 = 4
h(x) ⇒ x = -(-12)/2(-3) = 12/-6 = -2
Rank from least to greaters: -2, 0, 4 ⇒ h(x) ; f(x) ; g(x) CHOICE D
The correct answer would be A. Hope this helps!
I hope this helps you
x^2 =125/4-121/4-11
x^2=4/4-11
x^2=1-11
x^2= -10
x= i.square root of 10
