Question

For the given equation find the value a, b, and c, determine the direction in which the parabola opens and determine the y-intercept. Decide which table best illustrates these values for the equation:

y=x^2-6x

Answer 1

Answer: Table A

Explanation:

The coefficient of x^2 is 1, the coefficient of x is -6, and the constant is 0. This means that a = 1, b = -6, and c = 0.

• This eliminates tables B and C.

Now, we need to determine if the graph opens up or down to differentiate between A and B. Since the coefficient of x^2 is positive, the graph opens up.

• Thus the answer is Table A.
