"Use the table of values that represent points on the graph of a quadratic function. By determining the vertex and axis of symmetry, find the general form of the equation of the quadratic function.

Question

The table looks like this

X -2 -1 0 1 2

Y 1 0 1 4 9

Answer 1

y= (x+1)^2

axis of symmetry is x=-1

vertex is (-1,0)

Just plot the points, it's fairly obvious

it's the simple y=x^2 standard parabola shifted left by one unit
