Answer:
D(4) = -18
Step-by-step explanation:
D(n) = D(n – 1)(-6)
D(1) = 1/12
D(2) = D(2 – 1)(-6)
D(2) = D(1)(-6)
D(2) = 1/12 * (-6)
D(2) = -6/12
D(2) = -1/2
D(3) = D(3 – 1)(-6)
D(3) = D(2)(-6)
D(3) = -1/2 * (-6)
D(3) = 6/2
D(3) = 3
D(4) = D(4 – 1)(-6)
D(4) = D(3)(-6)
D(4) = 3 * (-6)
D(4) = -18

<h3>What is defined as the quadratic function?</h3>
A quadratic function is one of the following: f(x) = ax² + bx + c, where a, b, and c are positive integers and an is not equal to zero.
- A parabola is a curve that represents the graph of a quadratic function.
- Parabolas can open up or down, and their "width" or "steepness" can vary, but they all share the identical basic "U" shape.
- A quadratic equation is defined in mathematics as an equation of degree 2, which means that the highest exponent of the this function is 2.
As per the given question;
f(x) = x²
Now, we have to estimate the value of the function;
= f(x) + f(x) + f(x)
Substitute the value of f(x).
= x² + x² + x²
= 3x²
Thus, the value of the given function is found as 3x².

Yo sup??
Back to trigonometry again
apply sinx formula
sin49=GH/GI
GH=sin49*8
=6.0
Hope this helps.
