A student named Rachel wrote the vertex equation for a quadratic function with a vertex at (-7, -6) and an a value of 4. vertex form: y =a(x-k)^2 +h. (h, k) = (-7,6) a = 4. this is not correct. explain the mistakes.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
