The point (-1, 3) is the turning point of the graph with equation y = x2 + ax + b,

Burka [1]

Answer:

The turning point of a parabola is the vertex

Vertex form of a quadratic equation: $\sf y=a(x-h)^2+k$

(where (h, k) is the vertex and a is the coefficient of the variable x²)

Given:

$\sf y=x^2+ax+b$
vertex = (-1, 3)

Therefore, a = 1

Substituting a = 1 and the given vertex into the equation:

$\sf \implies y=1(x-(-1))^2+3$

$\sf \implies y=(x+1)^2+3$

$\sf \implies y=x^2+2x+1+3$

$\sf \implies y=x^2+2x+4$

Therefore, a = 2 and b = 4
