f(x) = 2
-4x
Step-by-step explanation:
Step 1 :
Given, f(x) = a(x - h)2 + k
Point on the parabola is (3, 6)
Vertex (h,k) = (1,-2)
Step 2:
Substituting the vertex in the equation we have,
f(x) = a(x-1)2 -2
Substituting the point (3,6) in this we have,
6 = a(3-1)2 - 2 => 6 = 4a -2
=> 4a = 8 => a = 2
Step 3 :
Substituting the value for a and the vertex in the given equation we have
f(x) = 2(x-1)2 -2 = 2(x2 - 2x + 1) -2 = 2x2 - 4x
=> f(x) = 2
-4x which is the standard form
Answer:
X/5 - 5 = f(x) for the domain [0,infinity)
Step-by-step explanation:
Answer:
x = 45
Step-by-step explanation:
AB // CD,
∠AB0 + ∠COB = 180 {Co interior angles}
75 + ∠COB = 180
∠COB = 180 - 75 = 105
∠DOE =∠COB {Vertically opposite angles}
∠DOE = 105
In ΔDOE,
x + 30 + 105 = 180 {angle sum property of triangle}
x + 135 = 180
x = 180 - 135
x = 45
The answer is B. Binomial. :)
