Answer:
y= -2x²+4x.
Step-by-step explanation:
the common equation of the parabola is y=ax²+bx+c, where a, b, c - numbers.
1) the coordinates of the vertex are:
2) if according to the condition x₀=1, then b= -2a.
If according to the condition y₀=2, then
it means that c=a+2.
3) if b= -2a; c=a+2 and the point (3;-6) belongs to the given parabola, then it is possible to substitute them into the common equation of the parabola:
-6=3²*a-6a+a+2; ⇔ a= -2.
4) if a= -2, then b=-2a=4, and c=a+2=0.
5) if a=-2, b=4 and c=0, then the required equation of the parabola is:
y= -2x²+4x.
You plug in each of the 3 numbers as x so the table should have 3,5,8 as x and whatever you get for y for each one is your answer. I saw that you posted this 2 days ago, so you probably don't need help XD
Every yard has 36 inches, so 7 yards is 252 inches
Write as a system fx=5x=f-1x
Simplify the expression
fx=5x
f-1x=5x
Solve the equation
fx=5x
f-6x=0
Substitute the value of f into the equation
fx=5x
f=6x
Solve the equation
6x*x=15
Substitute the values
x=0
x=5/6
Solve the equation
f=6x0
f=6x5/6
The possible solutions are
f=0
f=5
