Question

Copy and complete the table of values for y=x^2+x what numbers replace a,b and c

Answer 1

a = 1, b = 1, c = 0

Explanation:

First, we need to find the vertex coordinates:

x (vertex) =

`x(vertex) = ( - b)/(2a) = ( - 1)/(2 * 1) = ( - 1)/(2) = - 0.5`

`y(vertex) = { (- 0.5})^(2) + ( - 0.5) = 0.25 - 0.5 = - 0.25`

Now, that we have the vertex coordinates, we need to pick three x values to either side of the vertex (as I did in the photo)
