Question

What are the values of a, b, and c in the function? List them in order with commas, such as 1,-2,3.
y = -2x2 + 5x - 4

Answer 1

you mean write this as \(ax^2+bx+c\)?

Answer 2

y = a x^2 + b x + c is the form for a quadratic.

y = (-2)x2 + (5)x + (- 4)

Compare and you can pick off the a, b and c in your equation.

Answer 3

read off the answer as \(a=-2,b=5,c=-4\)
