You can put this solution on YOUR website! Determine the equation of the quadratic function f(x) given that the vertex is (1,-5) and the function has a y-intercept at 3.
------
Form:: y = a(x-h)^2 + k
------
y = a(x-1)^2 -5
------
Note:: When x = 0, y = 3
------
3 = a(1) - 5
a = 8
------
Equation:
y = 8(x-1)^2 - 5
