Answer:
f(x) = (x +4)(x -1)(x -2)²
Step-by-step explanation:
The given points are all x-intercepts of the function. As such, each corresponds to a factor of the function. The x-intercept x=p corresponds to factor (x-p), for example.
Here, the x-intercept (2, 0) is repeated. It is said to have "multiplicity 2". That multiplicity value means the factor will have an exponent of 2 in the factored form of the function:
f(x) = (x -(-4))(x -2)(x -1)(x -2)
f(x) = (x +4)(x -1)(x -2)²
_____
<em>Additional comment</em>
When an x-intercept has even multiplicity, the graph will touch the axis there, but will not cross.

I am not sure if they are all correct but I hope I helped you a tiny bit
Answer:
<u>The equation is:</u>
<u>We have two points:</u>
A)
<u>Find the slope using these two points:</u>
- m = (99 - 68)/(620 - 310) = 31/310 = 0.1
<u>Use one of the points to find the y-intercept b:</u>
- 68 = 0.1*310 + b
- 68 = 31 + b
- b = 68 - 31
- b = 37
<u>The equation is:</u>
B)
<u>Find the value of y when x = 980:</u>
- y = 0.1*980 + 37
- y = 98 + 37
- y = 135
The total cost is $135
