Find a second-degree polynomial (that is, an equation of the form y =a + bx + cx2 d that goes through the three points (0, 1), (
Lostsunrise [7]

Answer:

y = 1 - x^2

Step-by-step explanation:

we're given three points (0,1),(1,0) and (-1,0). and and equation of a parabola

y = a + bx + cx^2

we can plug in each of the coordinates, and 3 equations

(x,y) = (0,1)

1 = a + b(0) + c(0)^2

a=1\quad\quad\Rightarrow A

(x,y) = (1,0)

0 = a + b(1) + c(1)^2

a + b + c=0\quad\quad\Rightarrow B

(x,y) = (-1,0)

0 = a + b(-1) + c(-1)^2

a - b + c=0\quad\quad\Rightarrow C

These are are three equations, well we can simultaneously solve them to find the values of a, b and c.

we already found that, a = 1. so we plug this value in the rest of the equations. we'll use equation B.

a + b + c=0

1 + b + c=0

b=-1-c

we can substitute this value of b and a = 1, equation C

a - b + c=0

1 -(-1-c) + c=0

1 +1+c + c=0

2+2c=0

c=-1

we can use this value of c back in b

b=-1-(-1)

b=0

hence our equation of the 2-degree polynomial will be:

y = a + bx + cx^2

y = 1 + (0)x + (-1)x^2

y = 1 - x^2

and this polynomial indeed passes through all the points (0, 1), (1, 0), and (-1, 0).

And since these are the only solutions to the simultaneous equation we solved (i.e. we have single values of a,b and c). there's no other possibility.
