Question

Create a unique parabola in the pattern f(x) = (x − a)(x − b). Describe the direction of the parabola and determine the y-intercept and zeros.

Answer 1

Hello what would you say the answer would be?

Answer 2

\[f(x)=(x-a)(x-b)=x^2-ax-bx+ab\]
\[f(x)=x^2-(a+b)x+ab\]
\[x^2>0\]
so parabola is open above.
when x=0,f(x)=ab
y-intercept is (0,ab)
zeros are x=a,b
