Question 10 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY

The vertex of a quadratic function is (6, 2), and the y-intercept of the function is (0,−70). The equation of the function in vertex form, f⁡(x)=a⁢(x−h)2+k, is shown. negative 70 is equal to a times open paren 0 minus 6 close paren squared plus 2 What is the value of A ?

Answer
A
2
B
negative 6
C
negative 2
D
6

Explanation

Substitute the y-intercept, (0, −70), into the vertex form using the vertex (6, 2): −70 = a(0 − 6)² + 2. Since (0 − 6)² = 36, subtracting 2 gives −72 = 36a, so a = −2. The correct choice is negative 2.
