Answer:
y = -2x^2(x - 3)
Step-by-step explanation:
<em><u>Preliminary Remark</u></em>
If a cubic is tangent to the x axis at 0,0
Then the equation must be related to y = a*x^2(x - h)
<em><u>(3,0)</u></em>
If the cubic goes through the point (3,0), then the equation will become
0 = a*3^2(3 - h)
0 = 9a (3 - h)
0 = 27a - 9ah
from which h = 3
<em><u>From the second point, we get</u></em>
4 = ax^2(x - 3)
4 = a(1)^2(1 - 3)
4 = a(-2)
a = 4 / - 2
a = -2
<em><u>Answer</u></em>
y = -2x^2(x - 3)
F= -3/5 x+2. Hope this helps

Answer:
The best approximation for the input value when f(x) = g(x) is x = 1.5.
Step-by-step explanation:
The function f(x) passes through the points (-3,1) and (0,1) and the point (1.5,1).
Therefore, the line has equation y = 1.
Now, the function g(x) passes through the points (0,-1), (1.5,1) and (3,3) points.
Therefore, the function g(x) crosses the line y = 1 at the point (1.5,1).
Hence, the best approximation for the input value when f(x) = g(x) is x = 1.5. (Answer)
