Question

Which function could the graph represent?
A) f(x) = x2 − 3x + 6
B) f(x) = 2x2 − 9x + 9
C) f(x) = 4x2 − 9x + 7
D) f(x) = −2x2 − 4x + 1

Answer 1

Answer:B

Step-by-step explanation:

The curve cuts the x-axis at points x=3/2 and x=3

F(x)= ((x-3/2)(x-3)

=x2-3x-3x/2+9/2

2x2-6x-3x+9

=2x2-9x+9
