Cubic Function Form:
y=
However here we only need ax^3 and +d
ax^3 makes the graph wider or skinnier or reflects it if negative.
So the first coefficient will be negative since we want to reflect it along the x axis
To move left three we will have to add 3 to the ax^3 giving us something like (x+3)^3
To move up 5 we set our y intercept (the +d part) to d=5.
Combing everything together gives us (x+3)^3+5
x=10

Answer:
Option d.
Step-by-step explanation:
The equation of the line of least squares is given as
where is the yield of wheat (bushels per acre) and x is the rainfall (in inches).
We need to find the expected number of inches of rain if the yield is 60 bushels of wheat per acre.
Substitute in the given equation.
Add 9.12 on both sides.
Divide both sides by 4.38.
The expected number of inches of rain is 15.78.
Therefore, the correct option is d.
Answer:A
Step-by-step explanation:
-7x^2-4x+20
-(7x^2+4x-20)
-(7x^2+14x-10x-20)
-(7x(x+2)-10(x+2))
-(7x-10)(x+2)
