Answer: y = -2x² + 920x - 84168
suppose: the equation of the parabola is y = ax² + bx + c
because the parabola passes through (126,0); (134,3200); (334,0)
=> we have the equations:
126².a + 126b + c = 0
134².a + 134b + c = 3200
334². a + 334b + c = 0
⇒ a = -2
b = 920
c = -84168
=> the equation of the parabola is y = -2x² + 920x - 84168
Step-by-step explanation:
We arrange the polynomial in terms of the power of the variable x in descending order. The highest order is three from -4x^3 and the lowest is 2 in which the order is zero. Hence, the polynomial becomes 4x^3 - 19x^2 -7x + 2. The third term in this sequence is -7x.
The scientific notation is 9.26138 ×10^3
