Question

The vertex of this parabola is at (3, -2). When the x-value is 4, the y-value is 3. What is the coefficient of the squared expression in the parabola's equation?

Answer 1

Hello :
the parabola's equation is : f(x) = a(x-3)²-2
the coefficient of the squared expression in the parabola's equation is : a
but ; f(4) = 3
3 = a(4-3)²-2
a-2=3.....a=5
f(x) = 5(x-3)²-2
