Question

The vertex of a quadratic function is located at (1, 4), and the y-intercept of the function is (0, 1). What is the value of a if the function is written in the form y = a(x – h)2 + k? a =

Answer 1

-3

Explanation:

Just took the assignment.

Answer 2

the vertex is at (h, k) so h = 1 and k = 4

1 = a( 0- 1)^2 + 4
1 = a + 4
a = -3
