The equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2
Find the diagram attached.
First, we need to get the zeros of the required function. The point where the curve cuts the x-axis is the zeros.
According to the graph, the curve cuts the x-axis at x = -2 and x = -4.1
The required factors will be (x+2) and (x+4.1)
Taking the product of the factors
f(x) = (x+2)(x+4.1)
f(x) = x²+4.1x+2x +8.2
f(x) = x² + 6.1x + 8.2
Hence the equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2

Step-by-step explanation:
Answer:
3 seconds.
Step-by-step explanation:
First calculate the time for each 20m length to pass through the bridge.
The train takes 3600 seconds to travel 144,000 m
So it takes 3600/144000 seconds to travel 1m.
and 3600 * 20 / 144000 seconds to travel 20 m.
As the train is 120 m long and there are 6 * 20 m in 120m the answer is:
3600 * 20 * 6 / 144000 seconds.
= 3 seconds.
The answer of the factored polynomial is
(X+2)(2x+1)
13×965= $12,545
each person pays $13 and 965 people come so you times them together to get the answer
