B) a=-1, b=5, c=0 would be the correct answer

Answer:

B) a= -1, b=5, c=0

Step-by-step explanation:

This is a quadratic equation.

From the form given y=ax^2+bx+c, it can be deduced that a, b and c are the coefficient of x^2, x and the constant respectively.

As such, when y=ax^2+bx+c is compared with

y= -x^2+5x,

a = -1, b = 5 and c = 0

Hence option B) a= -1, b=5, c=0 is right.
